Subject Re: Problems building Thermos

Not a silly question at all.  The error messages could definitely be more

Out of curiosity, do you have the python-dev package and compiler toolchain
installed into this image?  psutil has C extensions and it's possible that
pants simply can't get python to build them.

For mesos, one possibility of why it reports inability to resolve the
dependency could be pants itself attempting to build a python 2.6 executor,
so the 2.7 egg wouldn't be useful.  You could try ./pants build -i
'CPython>=2.7,<3'  src/main/python/apache/aurora/executor/bin:thermos_executor
to force pants to use python 2.7.  See if that affects whether or not it
can find a valid mesos egg.

Hope that helps!
