Problems compiling with IMAP-SSL on Solaris 8

Hi, I am trying to compile PHP 4.0.6 with IMAP-SSL on a sparc machine running Solaris 8. I am using thie uw-imap, and I am positive that it is working fine as IMAP-SSL. (I tryed on Netscape with SSL, and with openssl commands). Unfortunately, when I try to compile PHP with the --with-imap-ssl option, this is what I get: # ./configure --with-apache=/opt/src/apache --with-mysql=/opt/local/mysql --with-imap=/opt/src/imap --with-imap-ssl=/opt/src/imap/c-client --enable-memory-limit=yes --enable-debug=no --enable-track-vars (...) checking for IMAP support... yes checking for pam_start in -lpam... yes checking for Kerberos support in IMAP... no checking for SSL support in IMAP... yes configure: error: This c-client library does not support SSL. Recompile or remove --with-imap-ssl from configure line. Does anybody know what can I do to make it work? Thanks, Jose
