[pypy-dev] VerificationError after build

[Skip Montanaro]

My Linux machine at work is OpenSUSE 12.2, so I couldn't use a
pre-built binary.  I built PyPy 2.0.2 yesterday, then tried the
interpreter.  I got a couple VerificationError exceptions and never
got a prompt.  Looking more closely, I realized I was missing some
prerequisites I thought I had.  I installed everything I could find
from the list and fired up the build process again before heading
home.

It was done when I got in this morning.  I tried again.  Same result.
Since it was a compilation error, I thought I should mention what I
have available:

hornet% type cc
cc is /usr/bin/cc
hornet% type gcc
gcc is /opt/TWWfsw/bin/gcc
hornet% cc --version

For compatibility with our other bits of software, and with the PyPy
build itself, I would prefer to guarantee it uses gcc.  The error
message wasn't clear about what "cc" failed.  I skimmed the --help
output of rpython, then built it again with --cc=/.../.../gcc.  Third
try is a charm?  Not so much.  Can someone give me some suggestions
about debugging these tracebacks?

except when you don't expect it''
