Odd. Perhaps your system doesn't support libraries referring to other
shared libraries? (Seems unlikely, but...) In that case you'd be
getting the static libpq.a bound into libpgtcl.so, minus crypt of
course, and then this would happen.

If that's what's happening you should easily be able to tell from the
sizes of libpgtcl.so and libpq.so. On my machine, libpgtcl is actually
smaller than libpq (about half as big, in fact). If libpq is getting
bound into libpgtcl.so then libpgtcl.so would have to be bigger than
libpq.so. Which one is bigger on your machine?

Also, do you have any sort of utility that shows directly what a
program's shared library requirements are? For example, on HPUX
I can do

$ chatr /usr/local/pgsql/bin/pgtclsh
/usr/local/pgsql/bin/pgtclsh:
shared executable
shared library dynamic path search:
SHLIB_PATH disabled second
embedded path enabled first /usr/local/pgsql/lib
shared library list:
static pgtclsh
dynamic ../../interfaces/libpgtcl/libpgtcl.sl
dynamic ../../interfaces/libpq/libpq.sl
dynamic /usr/lib/libdld.sl
dynamic /lib/libcurses.sl
dynamic /lib/libc.sl
shared library binding:
deferred

$ chatr /usr/local/pgsql/lib/libpgtcl.sl
/usr/local/pgsql/lib/libpgtcl.sl:
shared library
shared library list:
dynamic ../libpq/libpq.sl

On Linux I think the corresponding command is "ldd".
