Hmm, okay. Well, I tried this:

$ ldd /usr/lib/libwx_gtk-2.1.so.11.0.0
	libwcsmbs.so.0 => /lib/libwcsmbs.so.0 (0x403ba000)
	libc.so.6 => /lib/libc.so.6 (0x403c0000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00000000)

Now, I would think it should be dynamically linked to libgtk, etc. And 

$ grep configure /usr/src/redhat/SPECS/wxGTK.spec
./configure --prefix=%{pref} --enable-threads --disable-std_iostreams
--disable-newgrid

No --disable-shared . Nor can I find any other evidence that indicates 
that it shouldn't have been dynamically linked with everything. Or
doesn't 'everything' include the GTK libs. Are there any wxWindows
users here who can comment?

No go. I tried 

   $ xhost localhost
   $ xhost + localhost
   $ xhost + 127.0.0.1
   $ xhost + matt@localhost (is this ok? the man page suggests it is)
   $ xhost + matt@127.0.0.1
   $ xhost +
   $ xhost + 500

Didn't work.

Interestingly, though:

$ xhost + matt@localhost
matt@localhost being added to access control list
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  109 (X_ChangeHosts)
  Value in failed request:  0xfe
  Serial number of failed request:  8
  Current serial number in output stream:  10

and:

$ xhost + 500
500 being added to access control list
$ xhost
access control enabled, only authorized clients can connect
INET:0.0.1.244    # huh?
INET:localhost
LOCAL:

Are these significant clues?
