No, I'm running bash.

I tried to eliminate all libraries from the octave build that are in
/sw/lib, but ran up against a problem. I need to use the FLIBS=-lg2c flag in
order to get past a failure in ./configure that specifies:

checking for Fortran libraries of g77... -lg2c
checking for dummy main to link with Fortran libraries... unknown
configure: error: linking to Fortran libraries from C fails

However, I searched my system and the only place libg2c lives is in /sw/lib.
So, it appears I need at least this library from /sw/lib in order to get
configure to work correctly.

Below is the output of otool on octave. It appears octave has pulled in
libreadline, libncurses, and libhdf5 from /sw/lib. I can get rid of the
first and last with configure options. However, the only place I found
libncurses was also in /sw/lib. I presume vecLib in /System/... is required.
Also I presume libz and libSystem.B are required. If not, let me know.
