courier-imap undefined reference

[CGI Guru]

Trying to get courier-imap running with this thing.  Pop and mysql working fine.  However, whenever I try to compile imap I get a whole string of the following:   /usr/src/vpopmail-4.9.10/vauth.c:70: undefined reference to `mysql_init' /usr/src/vpopmail-4.9.10/vauth.c:72: undefined reference to `mysql_real_connect' /usr/src/vpopmail-4.9.10/vauth.c:74: undefined reference to `mysql_real_connect' /usr/src/vpopmail-4.9.10/vauth.c:81: undefined reference to `mysql_query' /usr/src/vpopmail-4.9.10/vauth.c:86: undefined reference to `mysql_store_result' /usr/src/vpopmail-4.9.10/vauth.c:87: undefined reference to `mysql_free_result' /usr/src/vpopmail-4.9.10/vauth.c:88: undefined reference to `mysql_select_db' /home/vpopmail/lib/libvpopmail.a(vauth.o): In function `vauth_adddomain_size': /usr/src/vpopmail-4.9.10/vauth.c:121: undefined reference to `mysql_query' /usr/src/vpopmail-4.9.10/vauth.c:125: undefined reference to `mysql_store_result' /usr/src/vpopmail-4.9.10/vauth.c:126: undefined reference to `mysql_free_result' /home/vpopmail/lib/libvpopmail.a(vauth.o): In function `vauth_adduser_size': /usr/src/vpopmail-4.9.10/vauth.c:186: undefined reference to `mysql_query' /usr/src/vpopmail-4.9.10/vauth.c:189: undefined reference to `mysql_query' /usr/src/vpopmail-4.9.10/vauth.c:194: undefined reference to `mysql_error' /usr/src/vpopmail-4.9.10/vauth.c:199: undefined reference to `mysql_store_result' /usr/src/vpopmail-4.9.10/vauth.c:200: undefined reference to `mysql_free_result' /home/vpopmail/lib/libvpopmail.a(vauth.o): In function `vauth_getpw_size': /usr/src/vpopmail-4.9.10/vauth.c:240: undefined reference to `mysql_query' /usr/src/vpopmail-4.9.10/vauth.c:245: undefined reference to `mysql_store_result' /usr/src/vpopmail-4.9.10/vauth.c:250: undefined reference to `mysql_num_rows' /usr/src/vpopmail-4.9.10/vauth.c:260: undefined reference to `mysql_fetch_row' /usr/src/vpopmail-4.9.10/vauth.c:269: undefined reference to `mysql_free_result' /usr/src/vpopmail-4.9.10/vauth.c:272: undefined reference to `mysql_free_result' /home/vpopmail/lib/libvpopmail.a(vauth.o): In function `vauth_deldomain_size':   This is on RH 7.1 with mysql installed by rpm.  What's it looking for, where might it be, and how do I tell it how to find it?   Thanks.
