You can easily save all of your currently installed NetBSD packages for use on other machines by using pkg_tarup. Here's what to do.
1. Install pkg_tarup from pkgsrc. ie.. cd /usr/pkgsrc/pkgtools/pkg_tarup ; make install (as root)
2. Now you can now use pkg_tarup to create a tarball package from any currently installed package. Just do pkg_tarup [packagename]
Here is an example of how powerful this technique can be. With only a few lines of shell code we can put all the installed packages into a directory:
for PKGNAME in `pkg_info -e "*" | sort`; do
echo "Packaging $PKGNAME"
pkg_tarup -d "." "$PKGNAME" || echo "WARNING: Packaging $PKGNAME failed." 1>&2
