[Exim] Problem compiling 4.01 with ldap

I'm using what I guess to be a (new) standard Redhat 7.2 install.

The first sign of trouble is here...

>>> exim_tidydb utility built

make[2]: Entering directory
`/var/source/exim-4.01/build-Linux-i386/lookups'
gcc -c -O cdb.c
gcc -c -O dbmdb.c
gcc -c -O dnsdb.c
gcc -c -O dsearch.c
gcc -c -O ldap.c
ldap.c: In function `perform_ldap_search':
ldap.c:517: dereferencing pointer to incomplete type
ldap.c:518: dereferencing pointer to incomplete type
make[2]: *** [ldap.o] Error 1
make[2]: Leaving directory
`/var/source/exim-4.01/build-Linux-i386/lookups'

ldap stuff is /usr/include;/usr/lib and I've specified them in
Local/Makefile

thanks,
