Thank you for the help. However, there seems to be no "use_trac" on the AWS install.
On the AWS install " /opt/bitnami$ sudo find . | grep use_trac" returns nothing
On the OSX install I did previously, it returns ./Applications/trac-1.0.4-1/use_trac as you would expect
I guess its always possible I accidentally deleted it somewhere along the line How do I recover it?
Please, I'm also surpised that /opt/bitnami would be the trac installdir. Isn't that the root of any/all bitnami apps I might install. It seems more logical for the trac root to be "/opt/bitnami/apps/trac"
