I am having trouble with configuration of Apache if I use --with-imap in configuring php. I have imap-4.6-3 and imap-devel-4.6-3. Following are
the commands I make. When I come to configuring Apache for the second time I get:

[root@actinium apache_1.3.6]# SSL_BASE=../openssl-0.9.3a \
> EAPI_MM=../mm-1.0.9 \
> ./configure \
> --enable-module=ssl \
> --prefix=/usr/local/apache \
> --enable-shared=ssl \
> --activate-module=src/modules/php3/libphp3.a \
> --enable-module=php3

If I ship --with-imap in php configuration php works fine with Apache but I need the imap support for imp. Following are the command I have given to get these error...
