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

[John Magnotti]

It looks like there is simply an issue compiling pywavelets0.2.0. The
Portfile for pymvpa lists pywavelets as a dependency, thus removing
the +pywavelets does nothing.  So I see two fixes: 1) regress
pywavelets back to 0.1.6 or 2) remove the dependency on pywavelets.

Because Yaroslav mentioned that pywavelets is optional, either should
be fine. I went with #1, so I didn't have to mess with the pymvpa
Portfile. Instead, just change the version # in the py26-pywavelets
Portfile to 0.1.6, and adjust the checksums.


Assuming a vanilla macports installation.

cd /opt/local/var/macports/sources/rsync.macports.org/release/ports/
cd python/py26-pywavelets/
sudo open Portfile

change the version line to:
version             0.1.6

change the checksums to:
checksums           md5     d28ddb2c65f3c429f0d6bc72548584ab \
                    sha1    c12948178b5f4294408bb29424aa47fcd5d4fec9 \
                    rmd160  85cb2b0b6db8bf6b797ad36cb1341c673c442f18


I've attached a plain text file that goes over the steps in more detail.

Hope that helps,

John
