make install from /usr/pkgsrc/misc/screen gives at the end:

===>  Registering installation for screen-3.9.5
pkg_create: can't stat `/usr/pkg/bin/${PKGNAME}'

which seems to come from the line
bin/${PKGNAME}
in pkg/PLIST.

the file is there,
ls -l /usr/pkg/bin/screen*
lrwxr-xr-x  1 root  wheel      12 Oct  7 09:35 /usr/pkg/bin/screen ->
screen-3.9.5
-rwsr-xr-x  1 root  wheel  262144 Oct  7 09:35 /usr/pkg/bin/screen-3.9.5

so it looks like ${PKGNAME} isn't getting expanded.

I'm using the recent mk files and pkg tools.
make show-pkgtools-version
19990909


Is this sort of thing allowed in PLIST (variables)?
