Building custom gtk+ lib then program doesn't follow system's default theme.

["Keedi Kim" <keedi perl kr>]

Hi guys,

I just built gtk+-2.14.5 since 2.14.4 in Ubuntu 8.10 has a
GtkCellRenderCombo bug
(http://bugzilla.gnome.org/show_bug.cgi?id=558323)

Anyway I got brand-new stable release of gtk+.
and build my program again to linking new gtk+

Then I run my program, programs looks far more different from another
programs.
How could my program follows system's default theme?
Is there a general way to achieve this?

Thanks, :-)
