Hi, after building 1.9.1-p129 on cygwin I got 13:12:42 ~$ gem19 install RedCloth WARNING: RubyGems 1.2+ index not found for: RubyGems will revert to legacy indexes degrading performance. ERROR: While executing gem … (ArgumentError) string contains null byte (The full story with debug is below.) This could be an issue with our company’s HTTP proxy because we had issues with MD5 mismatches in the past and the debug seems to indicate issues with chunk sizes. Can anybody confirm that he / she can actually install that gem properly with this version of Ruby? 13:13:10 ~$ ruby --version ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-cygwin] Thanks!
