Hi Minh, and Hi Mac Experts,

Now I feel less lonely. I thought I am the only sage developer without
a Mac :-)

But seriously, I would appreciate if some Mac expert could try and
help me to hunt down the build problem on Intel Mac!

The reasons why I am puzzled:

* I understood that William did a successful test on many platforms,
presumably including Intel Mac, of a previous package version that now
is an optional package, installable by
 sage: install_package('p_group_cohomology')
AFAIK, I did not change the part that now fails to build.

* The error reported by John Palmieri was
{{{
ar rv /Applications/sage_builds/sage-4.1.1-binary/spkg/build/
p_group_cohomology-1.1/src/lib/libmtx.a os.o
ar rv /Applications/sage_builds/sage-4.1.1-binary/spkg/build/
p_group_cohomology-1.1/src/lib/libmtx.a profile.o
ar: /Applications/sage_builds/sage-4.1.1-binary/spkg/build/

p_group_cohomology-1.1/src/lib/libmtx.a(profile.o)] Error 1
make[2]: *** Waiting for unfinished jobs....
a - os.o
}}}

What does it mean, "Resource temporarily unavailable"? Does the Mac
try a parallel build, so that two different parts of the build process
try to write into libmtx.a at the same time? Is it a write permission
issue?

Best regards,
Simon
