Hello BF/Roland,

Thanks for the clarifications.

Regarding the download speeds I was getting with portmaster fetches (0.7 
kBps to 4.0 kBps), I immediately booted into Windows/Cygwin and did a 
wget from the same site portmaster was using. The speed I got from wget 
was ~ 35 kBps. This happened not just once but multiple times. Each time 
I did this, I had to interrupt portmaster. Finally I managed to get to 
install the wget port on FreeBSD itself. When I ran wget from FreeBSD, 
it reported comparable transfer rates (~ 35 kBps) from the same sites as 
portmaster was using.

I got a curl port from portsnap marked IGNORE. portmaster did not ignore 
it anywhere near gracefully enough and finally killed off all child 
processes and itself.

The IGNOREME way is fine for me for avoiding multiple ports I know 
beforehand I do not want to build. But if a portsnap update creates an 
IGNORE port, portmaster should be skipping it entirely rather than 
having to kill all child processes and itself. In my experience, this 
did not happen. Or maybe my system was badly broken already by that time.

Anyway, my system became so unpredictable that I had to reinstall 
FreeBSD. For the moment, I am avoiding portmaster till I can try it out 
on a dummy PC first.

BTW, I also tried portmanager and it segfaulted at the stage of 
generating a report.


Thanks for all the help.
