math/gfan: fix build with clang 19
Clang 19 has become more strict about errors in member functions, which
results in errors building math/gfan:
src/gfanlib_matrix.h:123:18: error: no member named 'vectormultiply' in
'Matrix<typ>'
123 | ret[i]=a.vectormultiply(b.column(i));
| ~ ^
The `vectormultiply` method has been commented out by upstream for
unknown reasons, but the `operator*` method that references it is also
never used, so stub it out.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.
Approved by: portmgr (tcberner)
Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
(Only the first 15 lines of the commit message are shown above )
math/gfan: pass maintainership
o Update URL in MASTER_SITES to current address
o Update MAINTAINER
o Remove post-patch target as it is not needed
- Use LDFLAGS instead of the non-standard variable
ADDITIONALLINKOPTIONS.
- Replace "${REINPLACE_CMD} 's,log2,gfan_log2,g'" by appropriate
patch files as the command triggers multiple warnings. log2 is
a macro defined in src/log.h. The name of this macro is in
conflict with the function log2 from math.h. To avoid errors
when compiling the code, the above renaming is necessary.
Furthermore, PHB 4.4.3 strongly suggests using patch files
instead of REINPLACE_CMD for static content.
o Sort pkg-plist alphabetically as required by PHB 3.2.2
o Shorten pkg-descr and make it less technical

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

This port requires a C++11-compatible compiler to build, so add
USES=compiler:c++11-lang to fix build on GCC-based architectures.
Also add LDFLAGS to the linking command so that it links against ports
libstdc++.
While here, add USES=localbase.

New ports: math/gfan, math/gfanlib
Gfan is a software package for computing Groebner fans and tropical
varieties. These are polyhedral fans associated to polynomial ideals.
The maximal cones of a Groebner fan are in bijection with the marked
reduced Groebner bases of its defining ideal. The software computes
all marked reduced Groebner bases of an ideal. Their union is a
universal Greobner basis. The tropical variety of a polynomial ideal
is a certain subcomplex of the Groebner fan. Gfan contains algorithms
for computing this complex for general ideals and specialized
algorithms for tropical curves, tropical hypersurfaces and tropical
varieties of prime ideals. In addition to the above core functions
the package contains many tools which are useful in the study of
Groebner bases, initial ideals and tropical geometry.
