Problem description:
====================

I'm trying to compile php-4.1.1 in a Slackware-8.x system with IMAP support. Slackware doesn't have imap libraries installed by default, and when trying to compile php using the option --with-imap, the configure script gives the error:

Cannot find rfc822.h. Please check your IMAP installation.

So I untared "pine4.44.tar.gz" from slackware-current sources which contains the file "rfc822.h" and the rest of imap libraries and used the option --with-imap=/path/to/imap/libs/ instead. Now the configure script complains with this error:

Cannot find imap library. Please check your IMAP installation.

I've STFW but I can't get php-4.1.1 to compile. Any help would be apreciated.


The configure command used:
