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

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.

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.
