autom4te: not found in FreeBSD 8.1RC1 - please help.

[Sam Wun]

 Hi,

 With FreeBSD 8.1 RC1,

 I got the following error when building cyrus-sasl2 in the Ports:
 ....
 configure: creating ./config.status
 autom4te --language=m4sh -B libltdl/config libltdl/config/ltmain.m4sh
 libltdl/config/ltmain.in
 autom4te: not found
 *** Error code 127

 Can anyone tell me how to resolve this problem?

 Your help is very much appreciated.

 Thanks
 Sam
