Python subprocess OSError

[symbiologist]

This might be a problem with just my machine, but I just did a fresh install of Ubuntu onto a new SSD so it's possible others are experiencing this as well.

I tried to install Rail-RNA using the downloaded installer as well as the command line script and run into this error with both. It seems to occur right after all the dependencies are downloaded and unpacked:

Traceback (most recent call last):
File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
"main", fname, loader, pkg_name)

errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1025, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

I've tried to do some Googling on this error and it looks like a potential Python 2 problem. I've tried reinstalling the most recent Python 2.7 which hasn't helped. Any ideas on what I might be doing wrong?

Thank you!
