Ah.  Yes, that was the problem.  Manually removing them worked.  Thanks.  

Yes, I did build from the repo source prior to installing yodl for
testing the sh compatibility patches.  

Seems to me that the installation code could use some improvement here.
The build was successful without yodl but the installation was not,
which was not really a surprise.  However, after installing yodl, the
installation still failed.  Even after doing a make clean or make
distclean, and reconfiguring.  That's not a very intuitive behavior.  

If those empty files are going to be created, I would suggest, when it
checks if they are empty, if yodl is installed, then automatically
delete and re-build them.  

You might also consider, if yodl is not installed, rather than exiting
with an error, perhaps printing a message to stderr that they are being
skipped and why, then continuing without error.  If you prefer it to
exit with an error by default in this case, then perhaps print a message
providing an alternate installation target that can be used to install
without the man pages.
