My pkg-config file contains:

Libs: -ljngl -lGL
Requires: libpng glib-2.0 xxf86vm

So i need to check if libpng, glib-2.0 and xxf86vm are available for
pkg-config. Is there a command to do this?

If the existing png-skeleton[1] doesn't do this already, you'll need

I tried and got the following:

jhasse@gutsy:~/svn/jngl$ package install jngl\ Library\ 0.5.package
 * trace:stub:59:verifying md5 of data payload
 * trace:stub:79:verified md5 of data payload
 * trace:stub:136:created working directory: /tmp/autopackage.2506126439
 * trace:stub:142:created payload directory:
/tmp/autopackage.2506126439/payload/@watteimdocht.de/jngl:0.5
 * trace:stub:145:created meta directory: /tmp/autopackage.2506126439/meta/@
watteimdocht.de/jngl:0.5
 * trace:stub:153:extracted metadata payload
 * trace:stub:162:set data payload filename: payload.tar.lzma
 * trace:stub:169:extracted data payload
jhasse@gutsy:~/svn/jngl$

But these messages all appeared just before the password. I checked the
installed file, and the only one coppied successful was jngl.pc. When i
select "No Password" it works fine, but that isn't usefull, because
pkg-config doesn't look in ~/.local.
