Yep. So would "mount".

This is a bug in the "requires:" field for the "mod_php4" package (it
should require "openssl096", not "openssl"). Stipe, please take note!

IMO, it would help the maintainer greatly if you could figure out the
correct way to call "rebase" and post a patch (the output of "diff -up
oldfile newfile") to this list.

FWIW, I doubt apache uses the Windows mechanism, since it uses mostly
stock Unix sources. I suspect your problem is the fact that the library
is indeed simply not in the right place.

I'm not sure if apxs even outputs anything. I suggest manually running
the apxs call that's in the postinstall script and seeing if the DLL is
copied (and if there's any output or return code). The intended result of
the postinstall script is fairly obvious: there should be a (globally)
rebased /usr/lib/apache/libphp4.dll present on your system. Playing with
the postinstall script components to achieve this result, and then
figuring out and documenting the minimal correct procedure would be a
useful thing to do.
