The gpg.ru(1) man page from the gnupg-1.4.16 distribution contains two lines:
.TH /home/wk/s/gnupg/doc/gpg.ru.sgml 1
No man page due to missing docbook-to-man
Please fix this, and perhaps even break 'make distribution' if the necessary
tools are not available, to avoid this problem from re-occurring. Thanks.
