Ad2p run breaks with "Illegal instruction" about adblock2privoxy HOT 3 CLOSED

The url https://easylist-downloads.adblockplus.org/malwaredomains_full.txt doesn’t exist, so adblock2privoxy is returning an error:

wget --max-redirect=0 -S --spider https://easylist-downloads.adblockplus.org/malwaredomains_full.txt 2>&1

See the MacPorts bash script here along with this list of easylist downloads for one way to handle this:

I do not see this issue on macOS.

This call isn't (directly) from any adblock2privoxy code, but undoubtedly from one of its Haskell import's. My best guess is that this is used for TLS checks. Lots of apparently related non-ghc issues like this out there. I'd advise to try to isolate which upstream thing is causing this and bump this upstream.
