Having some problem installing TCL and Expect in SUA

When I tried to install TCL on my vista with SUA (Ultimate and Enterprise) it
gives me an error like this:

/dev/fs/C/Users/test/tcl8414-src/tcl8.4.14/generic/tclClock.c: In function `Fo
rmatClock':
/dev/fs/C/Users/test/tcl8414-src/tcl8.4.14/generic/tclClock.c:314: error: `tim
ezone' undeclared (first use in this function)
/dev/fs/C/Users/test/tcl8414-src/tcl8.4.14/generic/tclClock.c:314: error: (Eac
h undeclared identifier is reported only once
/dev/fs/C/Users/test/tcl8414-src/tcl8.4.14/generic/tclClock.c:314: error: for
each function it appears in.)
*** Error code 1

Stop in /dev/fs/C/Users/test/tcl8414-src/tcl8.4.14/unix (line 857 of makefile)

Any suggestion on how to fix this? Thanks a lot.
