Ok. In my case nspr4.dll is located in the mozilla library directory.
The "components" directory, with xpti.dat and compreg.dat, is a subdirectory
of the the mozilla library directory.

I tried moving nspr4.dll to the "components" directory but got the same
behavior (and yes, I had to add "components" to the path in order for
the dll to be found).

Are you saying that I need to hack the source code for pyxpcom to do this?
If so where?

Would be nice to avoid hardcoding since I would like to be able to
move around the install between machines without recompiling.

What mystifies me is that I haven't really changed much from the build
procedure that I used 8 months ago, but now the behavior is different.

Is there anything in my build setup that possibly could have provoked
the new behavior?

By the way, my work-around is to remove compreg.dat and start mozilla
which then performs an auto-registration of components.
