Ah, it's getting EAGAIN from fds created from prior pipe() calls.  The other sides look like they were DUP2'd to fds 0&1, I'm guessing for a fork/exec().

Well, that isn't a big surprise - it's the way you would expect to get EAGAIN.  So ... evidently the GHC runtime is broken somehow on OpenSolaris?  I personally have no idea what's going on there, but while we're waiting for someone with a clue, here are a couple more random things to try:

Have you compiled and run separately?  instead of

...

runghc Setup.hs configure

 ghc --make Setup  Setup configure

It shouldn't make any difference on its own, but then you can try options on the compile, like "ghc -threaded", and runtime flags like "Setup +RTS -V0 -RTS"  I suggest that because it cuts down on signal interrupts from the runtime, and your symptoms suggest a signal interrupt.

That fixed the signal problem! Sadly that just gets me far enough to Setup +RTS -V0 -RTS build, which runs ghc, which then dies from the same signal problem :-(
