Issues installing with Brew 0.9.5

[nocode99]

On OS X 10.10.5 with Brew 0.9.5

I installed mackup with no issues and tried running 'mackup backup' and got this error:

Traceback (most recent call last):
File "/usr/local/Cellar/mackup/0.8.8/libexec/bin/mackup", line 9, in
load_entry_point('mackup==0.8.8', 'console_scripts', 'mackup')()
File "/usr/local/Cellar/mackup/0.8.8/libexec/lib/python2.7/site-packages/mackup/main.py", line 52, in main
if args['force']:
KeyError: 'force'

I was able to uninstall and then install with Pip instead and was able to backup with no issues.

I am experiencing the same issue (installed via brew v0.9.5), which occurs for both mackup backup and mackup restore:

  File "/usr/local/Cellar/mackup/0.8.12/libexec/bin/mackup", line 9, in <module>
