Hi, I have the following setup:

# ls -l /usr/pkg
lrwxr-xr-x  1 root  wheel  8 Feb 24 21:21 /usr/pkg -> /opt/pkg

# cat mk.conf
LOCALBASE=       /usr/pkg
PKG_DBDIR=       ${LOCALBASE}/db/pkg
PKG_SYSCONFBASE= ${LOCALBASE}/etc
VARBASE=         /var
PACKAGES=        /opt/netbsd_build/packages
WRKOBJDIR=       /opt/netbsd_build/objects
DISTDIR=         /opt/netbsd_build/distfiles

Used it for a long time years ago, but started using pkgsrc again
recently and noticed build issues with gtk2 and gtk3 due to missing
cairo.h and pango.h headers.

Suspect something is not buildlinking properly, but why is this an
issue now? Is it not possible to have buildlink wrappers dereference
symlink that is LOCALBASE? Symlinks are supposed to be transparent to
applications.

It's not a major issue, I can just change LOCALBASE to /opt/pkg. I'm
just curious as to what has changed over the years, it seems like a bug
or design issue.
