I think what you've done is correct -- i.e. it's not on the PATH for the 
users system.

For the most part, the PATH for the command line is added to the shell 
rc scripts, so if you are not running from a shell (i.e. from a py2app 
bundle) you won't have the additional entries on PATH (like /usr/local/bin).

I'm pretty sure there is a way to edit a plist somewhere to add to the 
PATH system (or user?) wide. However, if you're delivering an app 
bundle, you probably don't want to require your users to do this.

I may misunderstand your use case, but I think you could specifically 
search for the utility in places it might be expected to be found:

/usr/bin
/usr/local/bin
/sw/... (for fink)
/opt/... (for macports)

rather then expect it to be on the PATH.
