So, indeed, your patch is wrong.
Not saying it's correct, just saying it was the smallest tweak that got me past the build break.

Currently, the UML build seems to require that /lib be a symlink to /lib64. This is not the case on PLD, and occording to the Oct 31 post on uml-user it's not the case on CentOS either. I don't know what other distros it's not the case for. > Anyway, what it's doing could be correct enough to do... except we do the > linking with GCC!

I'm just saying what I needed to do to get it to build with what I had. Rob ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
