Could it be that this compilation failure is caused by a previous failed build/test attempt, where the 'clean' step has not been run? Python's setup.py, in detectctypes(), detects that ctypes/libffi must be configured if a certain file is not present in the build directory. It's certainly the case that the clean step wasn't run previously (because somehow, the connection to the slave was lost). However, this shouldn't cause the build to fail: it should be possible to invoke make over and over again, without invoking "make clean" in-between. The real problem seems to be that something (what?) is looking for /home/packages/python/buildarea/trunk.klose-debian-ia64/build/Modules/ctypes/libffi/src/prepcif.c

It's distutils newer_group function. And distutils does a good job at hiding the error. For a test I've removed prep_cif.c in my own sandbox, and started setup.py with DISTUTILS_DEBUG env var set. The result is appended to this email.

This file ought to be present, it is under subversion control.

The error on the buildbot could be a different one. Strange.

I "fixed" it by forcing a build for that builder on a different branch; this causes a complete cleanup of the build directory, and a fresh checkout.

Seems that this has helped, the compilation did succeed now.

If this happens again, we will have to investigate what happened.
