I just compiled newLISP on a quad-core machine. It took...4 seconds!
This is a case where it's actually faster to compile than to install from a repo.
Update: Thanks to the comment below, I can do it even faster:
1. Download the newLISP source:
2. Extract the archive.
3. cd into newlisp-x.x.x
5. make -j 4
6. (As root) make install
Steps 4-6 took about 10 seconds.
