I would much rather that previous snippet of code look something like:
if sys.scipypath: # Or some other flag/global/something
use whatever is indicated
set things up for using that path
use builtin blas_atlas
In addition, some of us do not trust anything in /usr for production
work. This is to help make our system administrators lives easier.
If I only use things from, say /tools, the sysadmins can completely
erase and reload workstations for the purposes of bug fixes, security
updates, etc. without disturbing my work. This prevents, "GAAAHHH!
You upgraded the machine and now everything is using Foo_1.1.1 instead
of Foo_1.1.0 and now everything is broken."
Most Linux distributions are particularly bad about this.
This affliction is also known as "Perl Hell". ;)
