ERROR: \$GALAXY_PYTHON is set, but what it points to is not a suitable

Python interpreter. This version of Galaxy requires either Python 2.4

or 2.5. Possible solutions:
|
|
* Unset \$GALAXY_PYTHON to let Galaxy attempt to find a suitable

Python itself
|
|
* Set \$GALAXY_PYTHON to a suitable Python interpreter.

\$GALAXY_PYTHON is currently set to: $GALAXY_PYTHON

your \$PATH to include it.
