Worth noting that the package only fails on ppc and ppc64.

Another thing is that fortran compiler doesn't return with a failure -- it just
seems to skip generating .mod file output for some reason. It is rather
unpredictable which .mod file doesn't get built (ie varies between the builds).

Seems like it's due to -j8 and the modules building concurently, due to poorly
specified dependencies of makefile targets. I tried a scratch build without
mflags, and it succeeded.

Comment 3 Jakub Jelinek 2007-12-07 11:31:47 UTC

That's just buggy Makefile.  Whenever you USE some_module, you need a Makefile
dependency on .o file which creates the corresponding *.mod file.
