Hi, Not sure if this is the right place to ask. GHC 6.10.3 source dist: ./configure takes about 10 minutes to look for DocBook DTD and another 10 to look for DocBook XSL directory. I was writing this e-mail thinking it had completely crashed. Any reason why it's so ridiculously slow? A look at 'top' says the CPU is mostly idle during this time, but xmllint is running.
