configure unfortunately does not include the tcl library 
for linking libpgtcl.so on AIX :-(

In the meantime Jacques, your tcl installation should have a shared 
tcl library (libtcl8.2.so) or better yet an *.exp, which you can include
in the above link command. 

In the shell manually execute the link, like:

cd src/pl/tcl
gcc -O2 -pipe -Wall -Wmissing-prototypes \-Wmissing-declarations  -Wl,-H512 \-Wl,-bM:SRE
-Wl,-bI:../../../src/backend/postgres.imp\-Wl,-bE:libpgtcl.exp -o \libpgtcl.so libpgtcl.a
-L../../../src/interfaces/libpq-lpq   -lc \  -L/usr/local/lib -Wl,-bI:/usr/local/lib/libtcl8.2.exp
 

The above addition could be generated with TCL_LIB_SPEC.
The -L/usr/local/lib is also essential to avoid runtime hassles,
why is this actually not automatic, since --with-libraries was used ?

Would a patch for src/pl/tcl/Makefile still be accepted for 7.2 ?
