Ted,

Congratulations on the new MacBook Pro! Sorry to hear you are having 
problems installing FB5 and FBtoC.

In FBtoC preferences, please check the Preferences. At the bottom, there 
is a button marked Advanced. When you press it, the drawer opens and a 
box marked "Path to Developer folder" is shown. Tick the box marked "Use 
compiler from Developer folder" and enter:

/Developer old

Also, in Xcode4, go to the Preferences. There is a tab called Downloads. 
In the Components list, you will see an item called "Command Line 
Tools". Is that shown as "Installed"? Not essential, but just checking 
to get a better feel for the problem.

Finally, if you are using a "Project" for your old app that previously 
compiled correctly, check the FBtoC settings in the Project as those may 
be different to the Preferences for FBtoC generally.

Kind regards,

Deep
