More precisely the built-in Lapack module. AFAICT this is because the
f90 files are not compiled with -fpic. My output:

If I update src/modules/lapack/Makefile.in to add $(FPICFLAGS) to the
.f90 compilation, then all is good. I assume you would also want to
add -g and -O2 here, so probably some other variable is better than
$(FPICFLAGS).

FYI,
Gabor
