1.1.15 fails to build using an identical layout to 1.1.14, which means something has changed with either the build dependencies or the way configure is working.
Here's the build failure I'm getting on amd64, but it fails on all arches: http://launchpadlibrarian.net/22606029/buildlog_ubuntu-intrepid-amd64.wine_1...
I'm going to sleep now, but hopefully I'll figure this out Valentine's day. In the meanwhile, 1.1.15 won't be available in Ubuntu packages just yet.
Thanks, Scott Ritchie
