[Magic-dev] Magic runtime problem

[Jeff Sondeen]

Hi, i solved a similar problem (getting the dir '/usr/lib64' to be
first in the search order) with this:


% diff ./lib/magic/tcl/tkcon.tcl~ ./lib/magic/tcl/tkcon.tcl
4a5,13

> puts stderr "old auto_path: $auto_path"
> set auto_path [lreplace $auto_path 2 2]
> puts stderr "new auto_path: $auto_path"
