Yes, it is very likely that it should help.

Two libraries linked with your ruby process
are not xenified (they use TLS).
These are libcrypt.so and libdl.so.
Also, in theory, your ruby process could use TLS itself.

I've just started CentOS 5.2 installation on Amazon EC2 
to check if ruby there uses the same libraries as yours do, 
and it uses!

[root@ip-10-250-7-83:~] ldd `which ruby`
        linux-gate.so.1 =>  (0xb7faf000)
        libruby.so.1.8 => /usr/lib/libruby.so.1.8 (0xb7eb9000)
        libpthread.so.0 => /lib/i686/nosegneg/libpthread.so.0 (0xb7ea2000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7e9e000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7e6b000)
        libm.so.6 => /lib/i686/nosegneg/libm.so.6 (0xb7e44000)
        libc.so.6 => /lib/i686/nosegneg/libc.so.6 (0xb7cfe000)
        /lib/ld-linux.so.2 (0xb7fb0000)

So it's very likely, that it is your ruby binary 
that uses TLS itself.

Could you try ruby from RPM?
