Bug #1438: dylib architecture error building 1.9.1-rc2 on osx10.5.6
http://redmine.ruby-lang.org/issues/show/1438

Author: Matthew Moss
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1 RC2
ruby -v: (miniruby) 1.9.1p0 

Attempting to build 1.9.1-rc2 on osx 10.5.6 in the following manner:

./configure --prefix=/usr/local --program-suffix=19 --enable-pthread --with-readline-dir=/usr/local --enable-shared
make



Much of the basic source builds just fine. After a while, though, I get the following:
