The move of X11 to /usr/local broke the compilation of acm if netpbm
is installed (pm.h from netpbm was used instead of the port's unrelated
local pm.h).
If this port does not compile with gcc-4, this is due to conflicting
declarations of the RPC server interface generated by rpcgen (statis
vs. non-static). This breakage must be fixed in rpcgen.
