Heheh, thanks for looking into it!

It should be “lib” instead of “libpurple”.  If you do that, perhaps the
‘install-libpurple’ phase is no longer needed because ‘gnu-build-system’
will take care of it.

As for the size, it seems that GTK+ & co. are pulled in.  Is there a way
to avoid it?  Perhaps this comes from the .pc file?

Thanks,
Ludo’.
