[petsc-users] linking PETSC with SSL

[Satish Balay]

Hm --with-ssl=0 should work. Can you do a fresh/clean build and see if the problem persists?

If so send configure.log make.log and test.log for this build.

BTW: 3.8 has better support for fortran usage - so you might consider
upgrading all the way to it.
