Comment(by drkirkby):
Actually, I think the C library too. The C library is very small anyway.
If Sage is linked with a new library, and someone has an older one on
their system, it could be a problem.
'ldd' might be useful to get the location on Solaris, Linux or HP-UX, but
not on OS X. Perhaps there is a more widely supported command, but I don't
know of it.
The configure script for gcc has these options.
{{{
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--libdir=DIR object code libraries [EPREFIX/lib]
}}}
so while one could guess at the location of libraries from the location of
the gfortran binary, it is not guaranteed to be right.
On Solaris, in 64-bit mode, it will be in a subdirectory too
{{{
