Yes, I can run insight from the build directory. So
currently I decide to use insight in this way, which
is good enough for me now :).

Yes, the error comes from that line, which is "  if
(Tcl_Init (gdbtk_interp) != TCL_OK)
   error ("Tcl_Init failed: %s",
dbtk_interp->result);"


But I am not sure how to pring the errorInfor---I have
tried puts stdout $errorInfo, and error("$errorInfo")
etc. but they seems to be not the right way.

I tried "export TCL_LIBRARY=/usr/local/share/tcl8.4"
before issuing insight or before make the
installation, but there occurs the same error.
