Hi, I recently downloaded galaxy and had some problems installing it on my machine (running Mac OSX 10.6.7 ). I've found a workaround to my problem, but I thought I should post here in case it is useful. I obtained the standard galaxy distribution using hg clone https://bitbucket.org/galaxy/galaxy-dist/ I then tried running sh run.sh but got; Traceback (most recent call last): File "/Users/iracooke/Sources/galaxy-dist/lib/galaxy/web/buildapp.py", line 81, in app_factory from galaxy.app import UniverseApplication File "/Users/iracooke/Sources/galaxy-dist/lib/galaxy/app.py", line 11, in <module> from galaxy.tools.imp_exp import load_history_imp_exp_tools File "/Users/iracooke/Sources/galaxy-dist/lib/galaxy/tools/imp_exp/__init__.py", line 6, in <module> from galaxy.web.base.controller import UsesHistory File "/Users/iracooke/Sources/galaxy-dist/lib/galaxy/web/base/controller.py", line 12, in <module> from galaxy.visualization.tracks.data_providers import get_data_provider File "/Users/iracooke/Sources/galaxy-dist/lib/galaxy/visualization/tracks/data_providers.py", line 16, in <module> from bx.arrays.array_tree import FileArrayTreeDict File "numpy.pxd", line 119, in init bx.arrays.array_tree (lib/bx/arrays/array_tree.c:11323) ValueError: numpy.dtype does not appear to be the correct type object I googled this error and found a post suggesting that I try virtualenv ... I tried that but it made no difference. Python --version returns 2.6.1 After some digging I tried rescrambling the numpy and then the bx_python egg. After rescrambling the latter sh run.sh worked. Anyway I'm not sure if other mac users have had similar problems. In my case I'm pretty sure I had installed things with easy_install in the past ...but I assume using virtualenv would have solved that problem. Ira
