To the other: $ strace -e file python -c 'from xml.etree import cElementTree' 2>&1 | grep libexpat.so open("/lib/libexpat.so.1", O_RDONLY) = 5 ImportError: /usr/lib64/python2.6/lib-dynload/pyexpat.so: symbol XML_SetHashSalt, version EXPAT_2_0_1_RH not defined in file libexpat.so.1 with link time reference This seems to be the cause of all this I guess. Any other idea on how to resolve this specific one? :) Thanks for you time!
