i proxychain hanno improvvisamente smesso di funzionare

Quando eseguo qualche programma con proxychains , mostra un errore come di seguito:

%> proxychains brew update
[proxychains] DLL init: proxychains-ng 4.11
[proxychains] DLL init: proxychains-ng 4.11
dyld: warning: could not load inserted library '/usr/local/homebrew/Cellar/proxychains-ng/4.11/lib/libproxychains4.dylib' into library validated process because no suitable image found.  Did find:
    /usr/local/homebrew/Cellar/proxychains-ng/4.11/lib/libproxychains4.dylib: mmap() error 1 at address=0x10E5A3000, size=0x00006000 segment=__TEXT in Segment::map() mapping /usr/local/homebrew/Cellar/proxychains-ng/4.11/lib/libproxychains4.dylib
[proxychains] DLL init: proxychains-ng 4.11

Qualche idea?

1. Disinstallare proxychains-ng brew uninstall proxychains-ng.
2. proxychains-ng richiede Xcode 7.x per la compilazione, build con Xcode 8 causerà questo problema. Correre xcode-select per cambiare la versione dello strumento da riga di comando Xcode, nel mio caso sudo xcode-select -s /Applications/Xcode7.app/Contents/Developer.
3. Reinstallare proxychains-ng brew install proxychains-ng.
