pgtcl installation problem

[Michael Talbot-Wilson <mtw(at)view(dot)net(dot)au>]

I have installed postgresql 8.2.0 and pgtclng 1.5.3 but the
installation of pgtclng 1.5.3 is faulty.  I hope someone can tell me
what I'm doing wrong.

I try to run this script (named see):

      #!/usr/local/bin/tclsh
      package require Pgtcl
      set fd [pg_connect -conninfo "host = localhost dbname = mtw"]

and get this response:

couldn't load file "/usr/local/lib/pgtcl1.5.3/libpgtcl1.5.3.so":
/usr/local/lib/pgtcl1.5.3/libpgtcl1.5.3.so: undefined symbol:
lo_export
    while executing
"load /usr/local/lib/pgtcl1.5.3/libpgtcl1.5.3.so pgtcl"
    ("package ifneeded" script)
    invoked from within
"package require Pgtcl"
    (file "./see" line 2)

With nm /usr/local/lib/pgtcl1.5.3/libpgtcl1.5.3.so I see

         U lo_close
         U lo_creat
         U lo_export
         U lo_import
         U lo_lseek
         U lo_open
         U lo_read
         U lo_tell
         U lo_unlink
         U lo_write
         U memcpy@@GLIBC_2.0

but

00005740 T Pg_lo_close
00004f80 T Pg_lo_creat
00004a70 T Pg_lo_export
00004bd0 T Pg_lo_import
000051c0 T Pg_lo_lseek
00005860 T Pg_lo_open
00005560 T Pg_lo_read
00004e40 T Pg_lo_tell
00004d20 T Pg_lo_unlink
000053e0 T Pg_lo_write

This is on Linux, fairly up-to-date.

Hope someone can help.  I have been using an earlier version of pgtcl
with postgresql 8.1 but now I'm lost and stuck.

Dunno why I see
         U memcpy@@GLIBC_2.0
because I have /lib/libc-2.4.so.  But I have very little understanding
this stuff (the linker).
