[LINUX] pkgsrc ignores installed depends

[Dario Niedermann <dnied%tiscali.it@localhost>]

Hi,

I use pkgsrc on Slackware, and I'm having trouble getting pkgsrc to find
the dependencies that are already installed on the native system.

For example, I'm trying to build VLC and I get this:

------------------------------------------------------------
pkgsrc/multimedia/vlc# setenv PKG_OPTIONS.vlc 'x11 sdl faad'
pkgsrc/multimedia/vlc# bmake
        ...
        ...
=> Full dependency SDL>=1.2.10: NOT found
        ...
        ...
------------------------------------------------------------

But I have sdl 1.2.13 installed via my distro's package system.

After RTFM, I put the following lines into /usr/pkg/etc/mk.conf:

        PREFER_PKGSRC?=
        PREFER_NATIVE?=         yes
        X11_TYPE?=              native

But it didn't help pkgsrc realize what's already installed.

Thanks in advance for your suggestions.
