I just tried it out. Scanning went well but building did not.

libnbcompat, which is the first package built, fails with

mkdir: /usr/pkgsrc/pkgtools/libnbcompat/work: Read-only file system
*** Error code 1

Stop.
make: stopped making "all" in /usr/pkgsrc/pkgtools/libnbcompat

This is weird because the config file (see attachment) specifies WRKOBJDIR. Any ideas?
