As I am having to reinstall netbsd, I was able to find something 
very interesting regarding comp.tar.gz.  Every time I install it using 
the install script from the miniroot, I get the following (here I 
downloaded/installed comp.tar.gz alone (I've already installed the other 
sets) so I could track the error down):

[...]
./usr/share/mk/bsd.subdir.mk
./var/db/libc.tags

gzip: stdout: Broken pipe
tar: child returned status 1
Extraction complete

Extract more sets? [n]

I really do not know what is going on, but will *try* to download 
comp.sys.gz and uncompress it by hand to see whether that will make a 
difference.
