Hi Python folks,
As part of a build system I work with, my group installs
multiple Python packages via source using easy_install. One such issue
I've seen before in the past is that when using multiple easy_install
instances (via multiple make jobs), the last instance that opened up
easy_install.pth records its changes; the file should contain entries
for all packages installed by easy_install.
easy_install doesn't support simultaneous parallel installations to
the same target directory, and there are no plans at the moment to
add that support.
Note, however, that if you use the -m (--multi-version) option, then
easy_install will not save the .pth file unless there was already a
default version of the target package present. However, if you begin
by deleting the .pth file altogether, then using -m will avoid
creating or updating it.
Of course, the downside of -m is that you will not be able to access
the installed packages except via setuptools-built scripts or by
using explicit require() calls.
