ISTR that this was not done by purpose, but I don't remember the details.

Perhaps something like: when you want to install modules to extend it,
this version doesn't look in the pkgsrc paths so won't find them.

Also, it's small, so having two copies isn't too bad.

Does anyone else remember?

Anyway, if the result is that this change is fine, please also update
pkgsrc so it makes proper use of it.

Thanks,
 Thomas
