Re: sage 5.2 build failed - some python module libraries were not installed

[Stephan E.]

All right, I figured it out.

It was my ~/.pydistutils.cfg that interfered with the installation. 

So python libraries were not installed in the sage tree.

However, shouldn't that be documented or dealt with?

In fact, there is also a quite old ticket on that one in trac:

I tried to build sage 5.2 from source but it failed when installing python-2.7.
I figured that python did not find some modules since they were actually not installed (but they were built!) into the sage tree.

Here is a relevant part of install.log:

Error installing package python-2.7.3.p0

However, I found the missing modules in spkg/build/python-2.7.3.p0/src/build/lib.linux-x86_64-2.7 and copied them into local/lib/python/lib-dynaload where I found them in my previous installation.
Now the building process continued (it's not done yet, so we will see).

However, I did not figure out why these libraries have not been installed.
Any ideas?

Thanks,
Stephan
