net-irc/kvirc-4.0_pre3831 and pre4000 fail to build with USE="-crypt". This worked with the current stable version pre3636. I came to this beacause of the stablereq bug #304009.
Created attachment 221635 [details] buildlog from net-irc/kvirc-4.0_pre3831 with USE="-crypt"
Does this problem occur with 4.0_pre3921 or 4.0_pre4000?
This happened to me on any newer version than pre3636! Ok, i admit, i haven't tested the 9999-version! ;-)
Could you report this problem e.g. in #kvirc?
"crypt" USE flag has been removed.
