Comment(by drkirkby):
Having looked at the error message, it would appear the library can't be
found. But it does exist as the place expected.
{{{
drkir...@swan:[~] $ file gcc64/sage-4.3.1.alpha2/local/lib/libgmpxx.so.3

}}}
Appending /export/home/drkirkby/gcc64/sage-4.3.1.alpha2/local/lib/ to
LD_LIBRARY_PATH_64 gets past the issue with GMP, though it does not allow
Linbox to build fully.
{{{

So it is happy with gmp.

}}}
So Linbox ultimately fails to build for another reason, but the GMP issue
can be circumvented.
I think with hindsight, it would have been better for 64-bit libraries in
Sage on Solaris to have been put in $SAGE_LOCAL/lib/sparcv9 or
$SAGE_LOCAL/lib/amd64 as appropriate.
Probably adding a new variable inside sage-env called LD_LIBRARY_PATH_64
and making that point to $SAGE_LOCAL/lib/ will do the trick. That will
cause the linker to look there for 64-bit libraries.
