>Description:
If you have PKGSRC_LOCKTYPE=sleep or PKGSRC_LOCKTYPE=once in your /etc/mk.conf,
'make depends' causes dead lock.

In PKGSRC_LOCKTYPE=sleep case:
ryoon@brownie: /usr/pkgsrc/audio/pulseaudio
$ make depends
=> Lock /usr/tmp/pkgsrc/audio/pulseaudio/work/.lockfile acquired for ``depends'' on behalf of process 29838
=> Lock acquire-bootstrap-depends-lock is held by pid 29838
=> Lock acquire-bootstrap-depends-lock is held by pid 29838
(repeated)

In PKGSRC_LOCKTYPE=once case:
ryoon@brownie: /usr/pkgsrc/audio/pulseaudio
$ make depends PKGSRC_LOCKTYPE=once
=> Lock /usr/tmp/pkgsrc/audio/pulseaudio/work/.lockfile acquired for ``depends'' on behalf of process 5848
ERROR: Lock acquire-bootstrap-depends-lock is held by pid 5848
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/audio/pulseaudio

Anyway if PKGSRC_LOCKTYPE is defined as once or sleep,
'make depends' does not work at all.

>How-To-Repeat:

For example,
$ cd /usr/pkgsrc/audio/pulseaudio
$ make PKGSRC_LOCKTYPE=once depends

>Fix:

I have no idea.
