Issues compiling tcl extension

[smugindividual]

I've downloaded the ldap extenstion for tcl from

http://www.sensus.org/tcl

(ldap.tgz)

I unpackaged it and configured with the following command(where /h/COTS?TCLTK is the location of th installed tcltk) (the error list is far worse without the flags):

./configure --enable-gcc --prefix /h/COTS/TCLTK --exec-prefix /h/COTS/TCLTK --libdir /h/COTS/TCLTK/lib

THEN I RUN MAKE AND GET THE FOLLOWING:
