You may need to do some housekeeping to remove some packages to work out a few dependency issues, however mine was swift as I only build gateways and lite boxes separately for one for HTTP, one for MySQL, one for Qmail.

So remember use GOOGLE to research your ERRs, or post them in here, don’t guarantee me to keep checking every hour, someone may come along like billy boy gates or steve balmer from M$ and they may know the answer

All the love to the *nix world keep awkin on!
