Latest fink unable to install xemacs on High Sierra

I did a fresh install of fink 0.43.1 on a High Sierra system, then installed texlive and all of its prerequisites. That all works fine. Then I try to add xemacs: fink install xemacs and I am met with this error:

-3.2# fink install xemacs
Information about 10475 packages read in 1 seconds.
Can't resolve dependency "system-xfree86 (>= 3:2.7.112-3)" for package "xemacs-21.4.22-9" (no matching packages/versions
found)
Exiting with failure.

The fink list command indicates the latest available version of system-xfree86 is 2.7.86-3. How can I get around this?
