Comment (by mf2k@…):

 Some more comments - this is not a complete review:
  - Add sha256 and rmd160 checksums and remove the sha1 and md5 ones unless
 provided upstream.
  - Since you are using portgroups, and those often add dependencies, you
 need to replace {{{depends_lib}}} with {{{depends_lib-append}}} and
 {{{depends_build}}} with {{{depends_build-append}}} to not overwrite them.
  - The python portgroup is normally only for python modules. However, if
 this port requires python to build, that is ok. However, you must choose
 only one python version. That should be 2.7 since that is the default in
 Macports.
  - You do not need to remove FORTRAN support in Macports. Please consider
 keeping it since many ports have this. But use the compilers portgroup
 which actually replaces the FORTRAN recipe. Unfortunately, that is not
 documented so look at a port like hdf4 or julia.
