It's already been done, uninstall and re-install pirut without success. The version removed end the re-installed one were at the same level For Centos-5.8 I've a test machine both are at the same level of update. If I do >>>print (sys.path) on the production machine, I get >>> import sys >>> print (sys.path) ['', '/usr/lib/python24.zip', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages'] And on the test machine I get >>> import sys >>> print (sys.path) ['', '/usr/lib/python24.zip', '/usr/lib/python2.4', '/usr/lib/python2.4/plat-linux2', '/usr/lib/python2.4/lib-tk', '/usr/lib/python2.4/lib-dynload', '/usr/lib/python2.4/site-packages', '/usr/lib/python2.4/site-packages/Numeric', '/usr/lib/python2.4/site-packages/gtk-2.0'] If I refer at Larry Martell message, he pointed that the problem was with sys.path If I look in ?usr/lib/python2.4/site-packages/ numeric in there on the test machine but absent on the production one I tried to re-install python-numeric.i386 0:23.7-2.2.2.el5_6.1 and nothig change; numeric is still not there On these facts, can somebody point me a solution? --- Michel Donais
