[Exim] LMTP compilation

Hello,
I'm trying to compile exim-3.36 under linux-2.4.7-10. It compiles
fine, and all the vital protocols/transports working, besides LMTP :(
When I'm trying to use the LMTP transport, I get 'LMTP driver not
configured' message.
TRANSPORT_LMTP=yes in the Local/Makefile is enabled, of course :(

Alexander.
