You're welcome :)

I'll need your help for going further. The following patch enable
libtool support, to build dynamic libraries in a portable way.
Curiously, I had to add AC_LANG_PUSH(C++)/AC_LANG_POP(C++) around header
checks, otherwise the compiler used for testing their presence was the C
compiler, instead of the C++ one, making test fails. This seems to be a
side effect of the AC_PROG_LIBTOOL macro.

teuchos build fine, but I got linking errors with epetra:

It seems I just need an additional -l flags, but I was unable to find
where are those symbols defined, apart some reference in
Epetra_LAPACK_wrappers.h, which seems to be some kind of fortran routine
indirection.

It may be caused by my blas library lacking C wrapper (cblas), but I
don't see why statically linked epetra library linking would have
succeded then.

Any help welcome, as my fortran knowledge average absolute zero :)
