Hello, i'm trying to install python module(twisted) which requires gcc to be installed. I'm very newbie to all server things, I've install gcc by using "yum install gcc" and then I tried to install "twisted" again. The console has thrown this line: twisted/runner/portmap.c:55: warning: implicit declaration of function ‘Py_InitModule’ twisted/runner/portmap.c:55: error: ‘PortmapMethods’ undeclared (first use in this function) twisted/runner/portmap.c:55: error: (Each undeclared identifier is reported only once twisted/runner/portmap.c:55: error: for each function it appears in.) error: command 'gcc' failed with exit status 1 ---------------------------------------- Cleaning up...

Thank you for help
