[pymvpa] MacPorts Updates

[James Kyle]

Greetings,

I have made the following updates to MacPorts that should should  
benefit users and solve several existing build issues:

- Updated the atlas (blas/lapack) pirt. .. this was a major source of  
build failures and glitches

- Updated Shogun to 0.7.3 (current)

- Updated pymvpa to 0.4.2

A draw back of ports is the inability to specify variants as  
dependencies. This was also a major source of installation issues. The  
respective ports now check to make sure that their dependencies have  
been compiled with the proper variants and if they have not, will  
cowardly refuse to install until the offending port has been upgraded.

I hope this leads to much smoother installation process for mac users.  
However, the best way to build the above tools to minimize unnecessary  
packages being installed and maximize success is as follows:

1. Install macports

2. sudo port selfupdate

3. sudo port install swig -php5 -ruby -perl +python 	(shogun users who  
want the r and octave interfaces should add +octave and/or +r to this  
list)

4. sudo port install shogun 				                (for r, octave, and  
elwms interfaces: +r +octave +elwms)

5. Add DYLD_FALLBACK_LIBRARY_PATH=${macports_prefix}/lib to your shell  
profile
*tip* the default ${macports_prefix} is /opt/local/. In that case, the  
library path would be /opt/local/lib

6. sudo port install py25-pymvpa +matplotlib


Please direct any bug reports to the MacPorts bug tracker: http://trac.macports.org/newticket
