Can not solve confict between both gallery and google map

gallery from GitHub - thomcowell/radiant-gallery: Photo Gallery Management System based on Radiant CMS (Ruby on Rails).
google map from git clone
http://github.com/dsci/radiant-google-maps-extension.git
vendor/extensions/google_maps

i got error “wrong number of arguments (2 of 1)” when i install
google map after i install gallery extension. i can install each of
them, but can not install them together. or if i install google maps
first then also have error with google map

thank you

There is almost certainly some method being pulled into the same class
via an include in each extension that has the same name but different
numbers of arguments (2 vs. 1).
