Sure? I fail to see a setting regarding runtime library paths in your
script (you explicitly avoid LD_LIBRARY_PATH at places). Does your
setup also work for Fortran and C++ programs that require the correct
runtime library from the external compiler (or are these external
compilers that hardcode the path themselves)?

Oh, it won't happen that easily that I stumble over an OS X system at
our place;-)

Btw., the practice of simply symlinking the runtime libs into pkgsrc's
prefix works nicely, too. I do wonder if that can be considered an
elegant solution. Actually, an argument can be made to _copy_ them: A
tarball of the pkgsrc tree would be self-contained and work even if the
external compiler directory is removed ...


Alrighty then,

Thomas
