Imap: /usr/bin/ld cannot find -limap

Hello list I run php4.06 with apache1.3.14 and postgresql7.1.3 I now need imap support with php, so I tried to recompile it.. The configure script works well, but when I try to make I have the following error: make[1]: Entre dans le répertoire `/usr/local/src/php-4.0.6' /bin/sh /usr/local/src/php-4.0.6/libtool --silent --mode=link gcc -I. -I/usr/local/src/php-4.0.6/ -I/usr/local/src/php-4.0.6/main -I/usr/local/src/php-4.0.6 -I/usr/local/apache/include -I/usr/local/src/php-4.0.6/Zend -I/usr/include/c-client -I/usr/local/src/php-4.0.6/ext/xml/expat/xmltok -I/usr/local/src/php-4.0.6/ext/xml/expat/xmlparse -I/usr/local/src/php-4.0.6/TSRM -DLINUX=2 -DUSE_HSREGEX -DUSE_EXPAT -DSUPPORT_UTF8 -DXML_BYTE_ORDER=12 -g -O2 -o libphp4.la -rpath /usr/local/src/php-4.0.6/libs -avoid-version -L/usr/local/pgsql/lib -R /usr/local/pgsql/lib stub.lo Zend/libZend.la sapi/apache/libsapi.la main/libmain.la regex/libregex.la ext/calendar/libcalendar.la ext/imap/libimap.la ext/pcre/libpcre.la ext/pgsql/libpgsql.la ext/posix/libposix.la ext/session/libsession.la ext/standard/libstandard.la ext/xml/libxml.la TSRM/libtsrm.la -limap -ldl -lpq -lcrypt -lresolv -lm -ldl -lnsl -lresolv /usr/bin/ld: cannot find -limap collect2: ld returned 1 exit status make[1]: *** [libphp4.la] Erreur 1 make[1]: Quitte le répertoire `/usr/local/src/php-4.0.6' make: *** [all-recursive] Erreur 1 I use a Debian system (2.2_r3 Potato), with libc-client4.7 and libc-client4.7-dev installed.
