[pymvpa] error py26-pywavelets installation on snow leopard Mac

[John Magnotti]

I'm with Yaroslav on this one, multiple versions of Python inside of
macports will almost certainly lead to compiler/linker errors. I
looked at the log file and it looks like it's trying to use python
2.6, which makes sense because you're installing py26-pywavelets, not
py27... Removing python 2.6 is a *bad* idea though, unless you know
all the things that depend on it. Further, removing 2.6 doesn't mean
the packages built for 2.6 will fall back on 2.7.

I'll try again tomorrow once I have my machine with me. I may remove
macports and try again from scratch so we can have the full process
documented. This should be a relatively easy setup, else I may have to
stop calling os x unix-like.
