In the last two days, fox-1.6.34 was checked into Macports.  Initially I 
got:

$ sudo port install fox
--->  Fetching fox
--->  Verifying checksum(s) for fox
--->  Extracting fox
--->  Configuring fox
--->  Building fox
Error: Target org.macports.build returned: shell command " cd 
"/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_x11_fox/work/fox-1.6.34" 
&& make all " returned error 2
Command output: FXFont.cpp:509: error: 'FC_WIDTH_SEMICONDENSED' was not 
declared in this scope
FXFont.cpp:510: error: 'FC_WIDTH_NORMAL' was not declared in this scope
...

After some googling, it was apparent this is related to the Xft2 
libraries.  After installing the Macports Xft2 (instead of relying on 
Apple's), it installs cleanly, does not segfault, and xfe also now 
works!  Again, this is on Tiger.

I have filed a bug report for fox:  https://trac.macports.org/ticket/17779

Also, gtk2 (+x11) still compiles and works fine, even though Xft2 pulled 
in the Macports xrender.
