Hi all, I have a problem about twisted-core library location. I downloaded and installed twisted-10.2-core(TwistedCore-10.2.0.tar.bz2) and names(TwistedNames-10.2.0.tar.bz2) from source code[1]. But python does not find "names" plugin. Because twisted-core has been installed under /usr/lib64/ but names is under /usr/lib/ defaultly.

I tried --prefix options to install method but i cannot pass the problem. Does anyone know how to fix the problem and why the names module is not installed under twisted-core library path. OS: RHEL 6.2 Thanks [1] http://twistedmatrix.com
