I use to have a directory .../tcl8.x/lib/pgtcl where I put a
symlink to the libpgtcl.so and the appropriate pgkIndex.tcl
file. The pgkIndex can be created by cd'ing into that
directory, starting a tclsh and issuing the command

pkg_mkIndex . ./libpgtcl.so

Once you have that, your Tcl scripts just need to do a

package require Pgtcl

No need for the user to set PGLIB or even know where it is
installed.
