Autoconf 2.49d test: Command not found

[John Poltorak]

After setting a number of environment variables and running 
sh ./configure
followed by make I got the following error at the end:-

make[1]: Leaving directory `/eval/autoconf-2.49d'
Making all in m4
make[1]: Entering directory `/eval/autoconf-2.49d/m4'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/eval/autoconf-2.49d/m4'

make[1]: :: Command not found
make[1]: Leaving directory `/eval/autoconf-2.49d/doc'
make: *** [all-recursive] Error 1


How do I find out which Command was not found ?
