[ubuntu-za] Google Gears Install failure

[Dr. Johan P. Prinsloo]

I encountered the following problem while trying to install Google Gears 
on Ubuntu 10.04. Google Gears provides off-line access for Google Calendar.
Install Failure Message:
"Google Gears could not be installed because it is not compatible with 
your Firefox build type (Linux_x86-gcc3). Please contact the author of 
this item about the problem."
Any advice?
