The workaround is simple: do a “make clean”. (That’s why our tests didn’t pick it up; they all start from clean.)

Since you're using RHEL4, you could try grabbing a GHC source RPM for Fedora and building that. It might take a bit of tweaking, but probably very little. (For instructions on building binary RPMs from source, Google around.) http://www.yahoo.com/r/hs
