BestMany thanks guys!!Concerning this, my LD_LIBRARY_PATH is declared somewhere, cause when I ommit setting it in my .bashrc file it has value of: /usr/bin:/usr/local/lib64:/usr/local/lib. Should I, and how?Fortunately it was becuse path in my .bashrc file. it was eithout backslash at the begining.So everything works now, regarding new installation, I am back to python blocks :).

why with LD_LIBRARY_PATH=/usr/bin:usr/local/lib64:usr/local/lib, GRC won't run, and with LD_LIBRARY_PATH=/usr/local/lib64. it works?The problem was bad LD_LIBRARY_PATH.Can anybody explain:My only guess for that is you have something left over in one of those directories from a previous installation that's pointing to a wrong version.

Just install 3.6.3, you should be fine.
Otherwise, manually browse through /usr/local and kill everything that
looks GNU Radio-ish.
