No, OP is correct here (assuming the project includes source from gemstash, as opposed to merely being something that links gemstash at runtime). You can certainly reuse code under the MIT license in an Apache-licensed project, but the license states clearly:
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
That is, you cannot remove the copyright notice nor the text of the MIT license.

(Yes, this is a very easy thing to fix.)
