I've tried all the 6.6 and 6.8 versions, trying to compile them on a RHEL-based supercomputer, and I always see this error when I run ./configure: -bash-3.00$ ./configure checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu Which we'll further canonicalise into: x86_64-unknown-linux checking for path to top of build tree... pwd: timer_create: Invalid argument configure: error: cannot determine current directory Is this a known bug with GHC, or is it my supercomputer? We have several supercomputers here running in production, so I can't really ask them to change the configuration just for me, but nonetheless I'd like to run on them.
