[Numpy-discussion] numpy installation issues

Mon Jul 7 09:34:04 EDT 2008

After installing the old binutils. (I hope this will not be necessary for
future numpy versions, that these can run on an unmodified cygwin install)
I managed to build and install.

Running numpy in python now gives some errors in the unit test:

Type "help", "copyright", "credits" or "license" for more information.
