libdl is a system library; it isn't part of GRASS. GRASS itself
doesn't include any dynamic libraries (although binary distributions
often include a copy of the GDAL dynamic library as a convenience).

The above error suggests that the NVWISH2.2 binary isn't compatible
with your version of MacOSX. I would guess that the version on the
OpenOSX CD was built on a newer version of MacOSX, and won't run on an
older version.

Maybe; I don't know enough about the Mac to provide a definite answer.

$GISBASE/tcltkgrass/main/tcltkgrass.tcl is bogus. It isn't actually
used by anything, and appears to be an outdated version of the
tcltkgrass script (in $GISBASE/bin) which is actually used.
