Can't "make" ghc on master

Hello guys, I'm trying a fresh compile from master. These are the steps I've taken: $ git clone http://darcs.haskell.org/ghc.git/ $ cd ghc $ ./sync-all --testsuite get followed by: cp mk/build.mk.sample mk/build.mk and finally: $ perl boot $ ./configure $ make But this is what I've got in the middle of make (just posting the relevant section): https://gist.github.com/adinapoli/6154219 As you can see I'm sandboxed inside hsenv, but I can't think of any reason this being the cause of the failure. Any ideas? Sorry for the naive question, A.
