The port test in an updated litecoin port fails with an unhelpful error 1, while a normal make is successful. I tracked this down to moc not being found during port test. However looking at the relevant config log lines I see that they are different during port test and normal make. I also see the same problem with the net-p2p/bitcoin port. It is interesting to note that moc,uic and rcc are affected, but lrelease and lupdate always have correct path.

For reference bug 222343 contains my updates to the litecoin, litecoin-utils and litecoin-daemon.
