phplib weirdness?

[bill parducci]

i setup a second installation of imp by copying my horde directory over
to a new virtual server on the same machine. when i try to run it i get
the 'Call to undefined function: page_open()..' error.

the docs indicate that this is a problem with my php.ini file, but i
cheked the settings and it *works* for the other installation on the
*same* machine?? i thought that maybe there was a security issue and one
of the lib files was not being included properly and causing this error.
doesn't seem to be the case (fyi: the default install of apache on
redhat serves up .lib files as text files to the browser -- prolly not
such a good idea from a security standpoint... :o(

any ideas?

thanks
