In case you need daily bk snapshots, they are here:

| Mmmm, no, I guess I won't.  I've just upgraded this machine to FC2, 
| and gftp is one of the many things broken by this, an strace exit of 
| trying to run gftp, most recent release:
| 
| writev(2, [{"/usr/bin/gftp-gtk", 17}, {": ", 2}, {"error while loading 
| shared libra"..., 36}, {": ", 2}, {"/usr/lib/libpangoxft-1.0.so.0", 
| 29}, {": ", 2}, {"undefined symbol: pango_fc_font_"..., 44}, {"", 0}, 
| {"", 0}, {"\n", 1}], 10/usr/bin/gftp-gtk: error while loading shared 
| libraries: /usr/lib/libpangoxft-1.0.so.0: undefined symbol: 
| pango_fc_font_map_get_type
| ) = 133
| exit_group(127)
| 
| And libpangoxft is this:
| [root@coyote root]# locate libpangoxft-1.0.so
| /usr/lib/libpangoxft-1.0.so.0.399.1
| /usr/lib/libpangoxft-1.0.so
| /usr/lib/libpangoxft-1.0.so.0
| 
| with the latter 2 links to the first one.
| 
| So I'd love to find this and fix it.  FC2 broke way more than it fixed 
| on this machine.  And yum update did run just fine once I got some 
| similar problems with libxml2 sorted.  Sorry.  Hints on this also 
| gratefully accepted of course.
| 
| In the meantime I'll cp my .config back to rc1 and see it it happens 
| with rc1.
