That doesn't make sense to me.  Can you prepare and send a tarball
(.tar.gz file) containing this Makefile.am file that causes the error
message, and the configure.ac file you're using?  Also, please show the
output of
  autoconf --version
  automake --version

This looks wrong, too.  automake should be complaining about the missing
'lib' prefix of 'main.la' in the lib_LTLIBRARIES line (unless you also
have a 'main_la_LDFLAGS = -module' line somewhere else, and the next
line should set main_la_SOURCES not _main_la_SOURCES.

Maybe this is some character encoding issue?  I'd need the files to be
able to say.
