It failed to build for me:

:info:build ld: library not found for -lf2c
:info:build collect2: error: ld returned 1 exit status

:info:build 1 error generated.
:info:build make: *** [obj/darwin/direct.o] Error 1
:info:build make: *** Waiting for unfinished jobs....
:info:build make: Leaving directory `/opt/local/var/macports/build/_Users_marbre_ports_math_taucs/taucs/work/taucs'
:info:build Command failed:  cd "/opt/local/var/macports/build/_Users_marbre_ports_math_taucs/taucs/work/taucs" && /usr/bin/make -j4 -w all PREFIX=/opt/local 
:info:build Exit code: 2
:error:build Failed to build taucs: command execution failed
:debug:build Error code: CHILDSTATUS 19021 2


f2c should be added as a dependency.

If it links with "-L/opt/local/lib -ltaucs", then it will find the libtaucs.dylib symlink* which points to the libtaucs.1.dylib dynamic library and it will hopefully work. If on the other hand it links with "/opt/local/lib/libtaucs.a" then it will fail because that file isn't there; probably in that case the build system should be fixed to link with the dynamic library.
