[Mongrel] mongrel and fastthread on ruby 1.9?

[Stephen Bannasch]

Is anybody testing mongrel on ruby 1.9. I just tried installing 
mongrel on trunk 1.9 and trunk rubygems and got this error compiling 
fastthread:

/Users/stephen/dev/ruby/1.9_trunk/bin/ruby extconf.rb install mongrel --no-rdoc
creating Makefile

make
gcc -I.
