[chimera-dev] Biopython paths

[Conrad Huang]

The problem you're encountering is due to Chimera having its own copy of 
Python instead of using the installed system version.  (We chose to 
bundle our own Chimera to avoid version issues, e.g., suppose you have 
2.6 installed and Chimera needs 2.7.)

In any case, there are a couple possible workarounds:

1. Specify PYTHONPATH in your environment to include 
C:\Python27\Lib\site-packages, so that Chimera picks up all the packages 
you've installed.  This _should_ work, but there may be hidden gotchas 
that we do not know about (yet).

2. Install BioPython into Chimera's version of Python.  There is a 
python.exe in the "bin" folder under the Chimera install location.  If 
you install BioPython using that copy of Python, Chimera will be able to 
use BioPython without you having to mess with sys.path.
