If the whole lapack section of addons was restructured like if os.environ.has_key('LINALG_LIB'): set things up for using that path elif os.path.exists('/usr/local/lib/atlas') use that elif os.path.exists('/System/Library/Frameworks/vecLib.framework') use that else use builtin blas_atlas
If I may ask, it would be great if /usr/lib/(atlas/ATLAS) were added to these default search paths, like the scipy setup.py file does.
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 else: if os.environ.has_key('LINALG_LIB'): set things up for using that path elif os.path.exists('/usr/local/lib/atlas') use that elif os.path.exists('/System/Library/Frameworks/vecLib.framework') use that else 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". ;) -a
