Comment(by was):
OK, I've found the problem. The build script is written in Python. Thus
the fortran spkg *depends* on Python. However, for me, when I built the
fortran spkg, it got built before Python, hence some random system-wide
wrong python was used, and this broke the build. This was a problem that
could have happened on many different systems in weird ways, so it's very
good that Robert Miller and I persisted and tracked this down, instead of
brushing it off.
The fix: change the deps file, and make sure to include a comment in the
deps file explaining this dependency.
One could also add a check that $SAGE_LOCAL/bin/python exists in this
spkg-install script.
Another good idea, would be to change the sage build system, so that when
if spkg-install is a Python script, but Python hasn't been built yet, then
an error is immediately raised. This would keep this problem from ever
happening again. I've opened a ticket: #9507.
