I was actually looking at this exact code very recently since I was
fixing the build system with Stage1Only a little last night.
We do something like this in ./ghc.mk:
----------------------------------------
define addExtraPackage
ifeq "$2" "-"
# Do nothing; this package is already handled above
else ifeq "$2 $$(GhcProfiled)" "dph YES"
# Ignore the package: These packages need TH, which is incompatible
# with a profiled GHC
else
PACKAGES_STAGE2 += $1
endif
endef
---------------------------------------
So it skips adding dph to the list of stage2 packages if GhcProfiled is 'YES'
Simon, this is speculation, but can you try:
$ make show VALUE=GhcProfiled
I think it's possible the value of GhcProfiled may have whitespace in
it, which would cause this `ifeq` to fail.

I try “sh validate” with profiled libraries and get
libraries/dph/ghc.mk:134: *** Cannot build profiled GHC with DPH; try deleting libraries/dph and trying again. Stop.
So I obediently remove libraries/dph, and try again. But that fails too:
Error: libraries/dph/LICENSE doesn't exist.
Maybe you haven't done './sync-all get'? at boot line 74, <PACKAGES> line 84.
Seems a bit Catch-22 ish. I’m not sure how to fix this.
Thanks
