[Exim] Trouble Compiling Exim with LDAP

I am trying to compile Exim with LDAP support:
OS: Solaris 2.8, Exim 3.30, LDAP - openldap downloaded from
sun/solaris/freeware.

I get the following message:


ldap.c: In function `perform_ldap_search':
ldap.c:481: dereferencing pointer to incomplete type
ldap.c:482: dereferencing pointer to incomplete type
*** Error code 1
make: Fatal error: Command failed for target `ldap.o'
Current working directory
/home/builder2/EXIM_LDAP/exim-3.30/build-SunOS5-5.8-sparc/lookups
*** Error code 1
make: Fatal error: Command failed for target `buildlookups'
Current working directory
/home/builder2/EXIM_LDAP/exim-3.30/build-SunOS5-5.8-sparc
*** Error code 1
make: Fatal error: Command failed for target `go'

Any idea?

Many thanks
