I've just tried an initial installation of Galaxy (galaxy_dist) on a Fedora 13 machine. When I try to run the setup.sh script I get the error below: Creating tool-data/shared/jars Traceback (most recent call last): File "./scripts/fetch_eggs.py", line 31, in <module> c.resolve() # Only fetch eggs required by the config File "/data/private/galaxy/galaxy_dist/lib/galaxy/eggs/__init__.py", line 284, in resolve egg.resolve() File "/data/private/galaxy/galaxy_dist/lib/galaxy/eggs/__init__.py", line 172, in resolve r = pkg_resources.working_set.resolve( ( self.distribution.as_requirement(), ), env, self.fetch ) File "/data/private/galaxy/galaxy_dist/lib/pkg_resources.py", line 565, in res olve raise DistributionNotFound(req) # XXX put more info here pkg_resources.DistributionNotFound: simplejson==1.5 Fedora 13 comes with simplejson v2.1.1. Is there really a strict requirement on v1.5 or should the test be >=1.5? Is there a way to parallel install different versions of this package if 1.5 is strictly required? Thanks Simon.
