Hey again. 
Actually I traced the problem down by myself. It was an nfs issue. The                    
pkgsrc was mounted from a linux nfs server, and apparently the hierarchy
got too complicated and it wrenched subs.sed. It's supposed to be a file, 
but it appeared as a directory on the server and with the size of 0.

Extracted pkgsrc locally and works fine. Now it's just that it eats a 
quarter of my flash...

Cheers.
