easyfw won't run

[Pigeon <jah.pigeon@ukonline.co.uk>]

Hi,

Trying to run easyfw I get:

Error in startup script: unknown floating-point error, errno = 84
    ("if" test expression)
    while compiling
"if { $tk_version < 8.0 } { ..."
    (file "/usr/local/bin/easyfw" line 11)

The offending code is:

#!/bin/sh
# the next line restarts using wish \
exec wish "$0" "$@"

# Daniel Roche, <daniel.roche@bigfoot.com>
# Ladislas HAJNAL pour l'adaptation à ipchains <hajnal@enac.fr>
#########################################################

if { $tk_version < 8.0 } {
    puts "easyfw need tcl/tk version 8.0 mininum , aborting !"
    exit
}

and yes, I do have tk 8.0 (8.0.4).

Any ideas? I am without a clue.
