hello group ,

I installed FreeBSD-5.2.1 , last week , and i'm still discovering this new 
OS , i like the ports mechanism , but i'm still not experienced yet to 
understand and  manage errors related to this tool ,

about error messages ; i was installing "cryptplug" to use the 
"gpgme-openpgp.so"  plugin for managing signing and cryptoraphy in K-mail ,
i runned make build in the directory  /usr/ports/security/cryptplug ,
and after some downloading and compliation i had this error message : 
- ---------------------------------------------------------------------------------------

It looks like the patch of the dependency help2man-1.29 failed .
i would like to know what is the reasonfor that , and what can i do to correct 
and have this dependency patched correctly.



Any Help or Comments are greately appreciated.


Regards.
