Re: problems about Installing multiple versions of gnuradio

You probably have conflicting configuration about paths in ~/.gnuradio;
hard to say, actually.

Generally, when installing in separate prefixes, it's no good idea to
have both prefixes in LD_LIBRARY_PATH etc at the same time - for any
given process, only one should be in there. That's no technical
challenge, though, since environment variables are always just
inherented from the spawning parent process.

Best regards,
Marcus
