ccpnmr-2.2.2 and relax-1.3.15

[Jack Howarth]

   Can I get someone to commit the updates for ccpnmr to 2.2.2 and
relax to 1.3.15? The first is in...

http://trac.macports.org/ticket/33964

and switches the ccpnmr package to build against python27 and gcc45. The gcc45
compilers are used because ccpnmr now has code that supports libgomp.
The relax 1.3.15 update is in...

https://trac.macports.org/ticket/34238

and switches the relax package to python27 which requires the wxPython
dependency to be switched to py27-wxpython-devel. It also contains some
additional cleanups to the dependencies and the addition of a test.run.
Thanks in advance.
