Ticket #3146 (closed bug: duplicate)
Testsuite for 6.10.2 fails if ghc is not already installed.
The testsuite for ghc 6.10.2 fails if ghc is not already installed, because building at least one of the utilities requires hsc2hs.
Attached are patches to the testsuite-6.10.2/mk/boilerplate.mk and testsuite-6.10.2/timeout/Makefile to fix this. The patches force the use of the newly built hsc2hs. (The changes handle hsc2hs in the same way ghc-pkg is handled.)
