Comment(by wjp):
Some more preliminary results:
It seems that adding {{{$SAGE_LOCAL/lib}}} to {{{$LIBRARY_PATH}}} as
{{{sage-env}}} does, might have unexpected effects:
On 64 bit gentoo:
{{{
$ export LIBRARY_PATH=/blah
$ gcc -print-search-dirs
[...]
libraries: =/blah/x86_64-pc-linux-gnu/4.1.2/:/blah/../lib64/
}}}
So {{{$SAGE_LOCAL/lib}}} does _not_ end up being searched by gcc in this
case. (But the non-existent {{{$SAGE_LOCAL/lib64}}} does.)
On 64 bit debian (Lenny), this is
{{{
libraries: =/blah/x86_64-linux-gnu/4.3.2/:/blah/../lib/
}}}
It looks like we're completely mis-using {{{LIBRARY_PATH}}}... Maybe it's
worth considering putting {{{-L$SAGE_LOCAL/lib}}} in {{{$LDFLAGS}}} in
{{{sage-env}}}.
