Description

This is with HEAD as of 2011-10-24. 0d6529f669104b6f22049d456a9600d949a09018

Looks like the alex and happy executables found during ./configure are not used when compiling libraries in stage 1.

kolmodin@kolmodin:~/code/ghc$ time PATH=/home/kolmodin/.cabal/bin:$PATH ./configure --prefix=/home/kolmodin/usr --with-ghc=/usr/bin/ghc

/usr/bin/alex is version 2.2

Note that it tried to use /usr/bin/alex while ./configure had found /home/kolmodin/.cabal/bin/alex.

    Pass alex and happy locations to ghc-cabal; fixes #5579

    We only use --with-alex / --with-happy if we know where alex / happy
    are. In particular, we don't need them when building from a source
    tarball.
