Unable to compile quick-lounge-applet

[Øyvind Hvamstad <oyvind hvamstad net>]

When I do make install in gnome/quick-lounge-applet/, the compiler
yells:

In file included from quick-lounge.h:29,
                 from dlg-pick-applications.h:26,
                 from dlg-pick-applications.c:32:
quick-box.h:47: parse error before `GnomeIconLoader'
quick-box.h:47: warning: no semicolon at end of struct or union
quick-box.h:51: parse error before `}'
dlg-pick-applications.c: In function `add_applications':
dlg-pick-applications.c:232: dereferencing pointer to incomplete type
dlg-pick-applications.c:292: dereferencing pointer to incomplete type

When I look at the source, the syntax is good and I'm not able to figure
out what causes this error. Please help!
