But, but... I do have libxext and libxext-devel installed... (and minimal works just fine as the bug says)
libXext-1.3.2-1.fc19.x86_64
libXext-devel-1.3.2-1.fc19.x86_64

Also strace shows:
open("/lib64/libXext.so.6", O_RDONLY|O_CLOEXEC) = 11
read(11, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0`7`U1\0\0\0"..., 832) = 832
fstat(11, {st_mode=S_IFREG|0755, st_size=77376, ...}) = 0
mmap(NULL, 2169112, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 11, 0) = 0x7f0a493ee000
mprotect(0x7f0a493ff000, 2093056, PROT_NONE) = 0
mmap(0x7f0a495fe000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 11, 0x10000) = 0x7f0a495fe000
close(11)                               = 0

The F18 system which doesn't have a problem with sato has:

libXext-1.3.1-3.20130524gitdfe6e1f3b.fc18.x86_64
libXext-devel-1.3.1-3.20130524gitdfe6e1f3b.fc18.x86_64


Cheers,
Stefan
