Is it OK to apply the following patch to autogen.sh?

revpath comes as part of the imake package.  There is no particular reason 
this should be installed on a system, and it's not obvious what package the 
user should install.  On top of that, the error message output by the script 
if it's missing isn't that helpful.

So: this is a small change to warn the user if it is missing.  I was as 
conservative as possible - not exiting with an error if "which" can't find 
revpath - because I don't fancy having lots of angry translators on my back 
because I broke something :-)
