Fail to resolve a kind of version conflict

[kana]

Steps:

1. Initial state:
   • Flavorfile:
     • flavor 'A'
     • flavor 'B'
     • flavor 'L'
   • A requires L ~> 0.3.
   • B requires L ~> 0.3.
   • L 0.4 is the latest version.
   • Run vim-flavor install.
2. Changes:
   • L 0.5 is released.
   • X 0.0 is released. It requires L ~> 0.5.
3. Add flavor 'X' to the flavorfile.
4. Run vim-flavor install.

Expected:

• L is upgraded to 0.5.
• X 0.0 is newly installed.

Actual:

• vim-flavor fails with the following message:

Found incompatible declarations:
  L ~> 0.3 is required by A
  L ~> 0.3 is required by B
  L ~> 0.5 is required by X
  L >= 0 is required by you
Please resolve the conflict.

Fixed. Use vim-flavor 1.1.5 or later.
