tcl 101

This line in my portfile:

    set builddir    [system -W ${topdir}/scripts "./findhost.sh $(exec ${topdir}/config.guess)"]

is giving an error

:error:activate Target org.macports.activate returned: can't read "(exec /opt/local/libexec/reduce-algebra/config.guess)": no such variable

I'm trying to pass the result of config.guess to another shell script findhost. Could someone point out the error?
