Re: [Visualpython-users] Mac installation question.

[Bruce S. <bas...@nc...>]

It's not a problem of not finding packages, since when you import
numpy you find numpy. The problem is that numpy can't find a resource
it needs.

I don't know what could be set up oddly on these Macs, but the trace
claims that ___memcpy_chk should be found in
/usr/lib/libSystem.B.dylib. So the first thing to do is to verify that
indeed this file is missing (or damaged?). Is it?

Note that to see /usr/lib in the Finder you need to use the Finder
menu Go > Go to Folder.
