Ruby Forum Redcloth > Build issues on Leopard

Hello,
I'm having some issues building r190 on Leopard (10.5.1):

$ rake

(I tried removing the -arch ppc flags from the Makefile, still 
segfaults)

The solution here was to use the -O1 instead of the default (generated) 
-Os
CFLAG.

Here's a patch (there may be better ways to do this with mkmf?):

Thanks!  Patch applied.
