The only idea that comes to my mind is to ask VERY KINDLY package 
maintainers to write some files (preferrably with a standardized name 
like "netbsd-*addendums*.txt"). Maintainers would work with them the 
same way they work with DESCR.
The files would contain a comparison of original documentation to how 
the package works in NetBSD.

I really liked the answer of Rene Huxel and personally I would recommend 
to directly copy-and-paste it into a 'netbsd-addendums.txt' file. :-)

Finally an apology: my problem was not in pam-ldap, but in a different 
package named PAM. Fortunately, the maintainer of both packages was the 
same person that could give me a big picure. In this case the point was 
to say that PAM, one of the required packages, doesn't work for system 
accounts, and that you need to do this and this to make other software 
to use PAM library and therefore also make PAM-LDAP work.
