Howdy, I'm doing an install from source on Mac OS X from the latest Phenix source packages. We install everything on an NFS mount so we can share it out to the workstations, so it's a little different than most OS X installs I suspect. Anyway, the installer was failing like this: (from the top level source directory) ./install --prefix=/programs/i386-mac/phenix/1.3-rc2 Which was getting me: configuring python compiling python csh: /programs/source/phenix/1.3-rc2/osx86/phenix-installer-1.3/bin/check_lib: No match. installation of python failed problem building main python library Looking at bin/install-from-source, it was failing on line 482: set py_lib = `$PHENIX_TAR/bin/check_lib $PHENIX_BUILD/base/Python.Framework/Versions/Current/lib/python*/config python` The reason for the failure is that the python framework installs with a lower case 'f': /programs/i386-mac/phenix/1.3-rc2/phenix-1.3-rc2/build/mac-intel-osx/base/Python.framework/ On a default HFS+ volume, which is case insensitive, this works just fine, but it fails when you try to install on a case-sensitive volume. Editing bin/install-from-source and :%s/Python.Framework/Python.framework/g seems to have fixed the build problem. -ben -- Ben Eisenbraun Structural Biology Grid Harvard Medical School http://sbgrid.org http://hms.harvard.edu
