Possible to require custom module dependancy on a specific dev version? Is it possible for my custom module to enforce it's dependability on a specific dev version of a particular module? 

E.g. my custom module, foo is dependant on variable module 7.x-1.1+26-dev.
Here is the info. 
Writing .info files (Drupal 7.x)

dependencies[] = exampleapi (1.x)


The above module requires any minor version of the module in the 1.x branch (1.0, 1.1, 1.2-beta4, etc.)

The dependencies[] property in the .info file can also optionally specify operators:

= or == equals (optional: equals is the default)
&gt; greater than
&lt; lesser than
&gt;= greater than or equal to
&lt;= lesser than or equal to
!= not equal to
