If your planning to use EAP,you know u need SSL but not openssl.You’ll need libssl-dev.This piece of information took me few days looking on the net and even compiled openssl by source (which doesn’t help).

If your planning to use ippool,you’ll need libltdl3-dev & libgdbm-dev.

So far,that all I need to record down.Just in case I need to reformat the whole OS for the 5th 6th 7th time.One more bad news for ya,freeradius can’t uninstall and I can’t replace it too.So…last resort,reinstall OS.
