Re: how to convert man pages?

[Giorgio Lando <patroclo7@xxxxxxxxx>]

Ok, now I have compiled and installed all the docbook-utils dependencies 
and docbook-utils itself.

I get very similar errors running docbook2man, but a couple of lines 
could be interesting:
 
offlineimap.sgnsgmls:/home/patroclo7/aur/offlineimap/src/offlineimap/offlineimap.sgml:1:60:W:cannot
 
generate system identifier for public text"-//OASIS//DTDDocBookV4.1//EN"
nsgmls:/home/patroclo7/aur/offlineimap/src/offlineimap/offlineimap.sgml:3:0:E:reference
 
to entity "REFERENCE" for which no system identifier could be generated

Does anybody know what the "system identifier for public text" is in 
this context and how it can be generated? Any insight from a non-debian 
based system can be particularly useful (for example from slackware).
Thanks in advance.
