compiling ghc HEAD fails on GenericTemplate.hs, looking for XBangPatterns
After "./configure" I type in "make" on the command prompt. Here is the resulting output:
[ecks@myhost ghc]$ make
===--- updating makefiles phase 0
make -r --no-print-directory -f ghc.mk phase=0 just-makefiles

===--- updating makefiles phase 3
make -r --no-print-directory -f ghc.mk phase=3 just-makefiles
===--- finished updating makefiles
