[tex-live] Problem with unicode math?

I get thee following error when using unicode-math 0.5e (fully updated TL2011):

 Undefined control sequence.
l.105 \xetex_or_luatex:nnn
                           { \cs_new:Npn \um_cs_compat:n #1 }

when compiling the file

%%!TEX TS-program = xelatex
%%!TEX encoding = UTF-8 Unicode
\setmathfont{XITS Math}
Here is an equation: \(x^{2}+y^{2}=z^{2}\).

Clearly the problem is happening while loading unicode-math.

Good Luck,
