[Rivet] Rivet installation troubleshooting

[Remus-Andrei Pãun]

Hello,

I am trying to install Rivet and I cam across this error:

AttributeError: '_Environ' object has no attribute 'has_key'
Makefile:665: recipe for target 'all-local' failed
make[2]: *** [all-local] Error 1
make[2]: Leaving directory '/home/remus/Workspace/RIVET/YODA-1.6.6/pyext'
Makefile:391: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/remus/Workspace/RIVET/YODA-1.6.6/pyext'
Makefile:512: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

Could you please help me? I don't know how to get pass it.

Thank you in advance.

Best regards,

Remus
