perhaps I'm too ignorant to use this, but I feel like I'm sooo close. I ran into numerous permissions issues with system gems, so I switched to homebrew and rbenv. I ran the following to create a subtheme:
compass create nistaurora -r aurora --using aurora/susy
all went well until the following line:
nistaurora/sass/style.scss (Line 2 of _aurora.scss: File to import not found or unreadable: respond-to.
Not sure where to look to sort that out.
*** LOCAL GEMS ***
Any help would be greatly appreciated. This looks like a great theme.
