I'm getting some mysterious DPH linking error when I am attempting a validate:

Urgh. That's the build race I thought I had fixed. It happens because the DPH vectoriser
needs dph-prim-seq to be compiled first before it can do its desugaring. If you run
validate single threaded or start it again like "sh validate --no-clean" it
should work. To run validate single threaded change the THREADS var in the script, or
export THREADS=1.
What machine were you compiling on? Does it fail on every validate run?
I'll see if I can get it to trigger the race again on one of mine.
I suspect you should check whether this bit of code in ghc.mk is working
correctly:
# Make sure we have all the GHCi libs by the time we've built
# ghc-stage2. DPH includes a bit of Template Haskell which needs the
# GHCI libs, and we don't have a better way to express that dependency.
#
GHCI_LIBS = $(foreach
lib,$(PACKAGES),$(libraries/$(lib)_dist-install_GHCI_LIB)) \
$(compiler_stage2_GHCI_LIB)
Cheers,
Simon
