depends_lib-delete broken ?

Could anyone verify what is going on here (or am I going nuts) ? DEBUG: can't set "depends_lib": invalid depspec: while executing "set depends_lib [ldelete ${depends_lib} $val]" (procedure "depends_lib-delete" line 5) invoked from within "depends_lib-delete port:gimp2" (procedure "variant-without_gimp" line 7) invoked from within "variant-without_gimp" invoked from within "catch "variant-${name}" result" Error: Error executing without_gimp: can't set "depends_lib": invalid depspec: Error: Status 1 encountered during processing. yves
