I'm running slackware64-current with the latest package updates. This morning I tried to build Firefox 21.0 but run into a problem apparently due to the Python package.
checking Python environment is Mozilla virtualenv... Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/mozilla-release/python/mozbuild/mozbuild/base.py", line 15, in <module>
from mach.mixin.process import ProcessExecutionMixin
File "/tmp/mozilla-release/python/mach/mach/mixin/process.py", line 29, in <module>
raise Exception('Could not detect environment shell!')
Exception: Could not detect environment shell!
configure: error: Python environment does not appear to be sane.
Any ideas as to what might be causing the problem? Thanks in advance
