My original dist file mistakenly contained object files and a gzipped man page.
(I simply forgot to make clean before rolling the tarball.)
Someone on your end enhanced the port Makefile to remove these post-extract
as a workaround.  I've since cleaned up the dist file, and updated the port 
Makefile and distinfo.  Here's the new tree:

# This is a shell archive.  Save it in a file, remove anything before
# this line, and then unpack it by entering "sh file".  Note, it may
# create directories; files and directories will be owned by you and
# have default permissions.
#
# This archive contains:
#
#	mcweject
#	mcweject/files
#	mcweject/files/pkg-message.in
#	mcweject/Makefile
#	mcweject/distinfo
#	mcweject/.Makefile.bak
#	mcweject/pkg-descr
