Python frameworks

[mark brethen]

With python27 port installed, and a reverse-engineered local portfile of py26-spyder, I was able to get spyder 2.0.12 running. I do not have multiple python frameworks installed on my mac. If I run python in a terminal window it uses:

Mark-Brethens-MacBook-Pro:bin marbre$ python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Which is installed by the mac os. However, when I run spyder, it shows in its console:

Python 2.7.2 (default, Aug  5 2011, 19:07:44) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "copyright", "credits" or "license" for more information.

/opt/local/bin contains 'python2.7', which is a symbolic link of the same name as the binary it links to. Spyder's pylint widget searches PATH for 'pylint' but I have 'pylint-2.7' in /opt/local/bin, which is a symbolic link; it does not have the same name as the binary it links to. Spyder recognizes IPython even though the symlink in /opt/local/bin has a different name. I don't have an explanation for this.
