Re: Dar binary doesn't run on Big Sur

Hi,

upx is used at building time by default but only if both:
- it is present on the system (in the PATH)
- the --disable-upx option has not been given to the ./configure script

Another point to take into account: you can transform an upx compressed
binary into its original form (non upx-compressed) by calling:

	upx -d <binary>

You can also check the nature of a binary using

	upx -l <binary>

not sure it can help for the "brew install dar" though...

If you have been using a binary from Softpedia it should be good to
report the problem there too as I'm not sure they read the dar-support
mailing list (though they surely read dar-news mailing-list).

Regards,
Denis
