Indeed when using dtrace we see that strdup and hence strlen are called on a NULL address:

sudo dtrace -n 'pid$target::_platform_strlen:entry { printf("%p", arg0) }' -c 'pkgin install mysql-client'
... [elided]
 6   5382           _platform_strlen:entry 0

pkgin upgrade also segfaults in the same way with a similar backtrace. I have installed it following the official commands (minus the gpg check).

Thanks for the tool, it is otherwise great.

Hmm, this may be NetBSDfr/pkgin#94. If you run pkg_add -U pkgin and then try again does it still fail?

[gaultier]

Yes, it seems to work now after running this command. Thanks.
