I'm currently compiling SAGE 5.5 and running in to the following errors (from the install.log):

68513 ==========================================================================      ==
68515             matplotlib: 1.1.0

68523                         * matplotlib.
68524 Error building matplotlib package.

However, if I check the installation of numpy in install.log, I see the following:

63222 Successfully installed numpy-1.5.1.p1

Why is matplotlib not finding numpy? Is there a way of forcing the path? This seems like something that should "Just Work".

My build process:

  1. Untar sage-5.5
  2. cd sage-5.5
  3. make

Absolutely this should "just work". Is there any other information about your machine and OS you can provide other than that already in your original message which might help someone track this down? (processor, unusual env vars set, etc.)

kcrisman, I've updated the original post (for organization's sake) with extra information including OS, kernel version, and environmental variables, minus a few that are not of interest to this case.

After some more fiddling, I've found the solution to my problem.

Sage's built-in version of Python will look, by default, without any prompting from environmental variables (as you can see from the list of environmental variables dumped above) took look in the ~/.local directory. If a .local exists for some reason and includes various python packages, SAGE will attempt to load them during the build process instead of the packages it has compiled as part of its build. I'm unsure if this is the intended behavior of the build process.

As a side note I have no recollection of ever creating or putting anything in the .local directory. Its removal had subsequently no visible effect on my local python installation.

I'll post a comment to that effect on sage-devel - it's possible this is a feature, and it's possible this is a bug.
