Normally, major version number changes indicate API changes, so pan 
wouldn't be expected to work (yet, it'll probably ultimately be updated to 
do so) with gtk-3, no.  However, gtk2 and gtk3 should be able to be 
installed together without interfering with each other so apps using both 
can be built and installed, and run.

But I'm not a dev and while I do run an experimental live-git build of pan 
from khaley's testing branch, I've not updated since just after 0.134, and 
I don't recall seeing anything about gtk3 updates in commits previous to 
my last update, so I don't know what pan's current gtk3 porting status 
might be or when it might be done.  However, I'm almost certain you'd need 
the live git version in any case, since I don't believe 0.134 supported it 
yet.

Perhaps Petr or KHaley will post with more explicit information.

Meanwhile, the normal "modern" installation and version detection method 
uses pkgconfig, with the package config data stored in *.pc files.  Here 
(gentoo/amd64 no-multilib), my installed gtk-2.22.1 package has the 
following *.pc files (amd64 so it's lib64 not lib, which is what it'd 
normally be for ia32 and many other archs):

/usr/lib64/pkgconfig
/usr/lib64/pkgconfig/gail.pc
/usr/lib64/pkgconfig/gdk-2.0.pc
/usr/lib64/pkgconfig/gdk-x11-2.0.pc
/usr/lib64/pkgconfig/gtk+-2.0.pc
/usr/lib64/pkgconfig/gtk+-unix-print-2.0.pc
/usr/lib64/pkgconfig/gtk+-x11-2.0.pc
