PHP4 with Imap on RH 7.2 fails

I try to build php 4.1 on RH 7.2, apache with Imap support I tried the RH supplied imap RPMs I tried to build the IMAP myself as described on php.net It does not work :-(( Now, configure with my usual stuff and --with-imap --with-kerberos --with-imap-ssl runs without any errors then I "make" and at the very End I get *** Warning: This library needs some functionality provided by -lc-client. *** I have the capability to make that library automatically link in when *** you link to this library. But I can only do this if you have a *** shared version of the library, which you do not appear to have. *** The inter-library dependencies that have been dropped here will be *** automatically added whenever a program is linked with this library *** or is declared to -dlopen it. I "make install" nevertheless and try to run httpd and I get Cannot load /usr/lib/apache/libphp4.so into server: /usr/lib/apache/libphp4.so: undefined symbol: mmdfdriver any Idea what's going wrong here? thanks Jens
