Cannot publish ethpm package with dependencies

Issue

Publishing an ethpm package (truffle publish) works nicely with self-contained contracts (i.e. those that do not import any other contracts), but I can’t get it to work with contract imports.

Steps to Reproduce

I am importing a Token contract here:

import "./Token.sol"; 

Note: importing from an ethpm install (i.e. import "tokens/Token.sol") has the same effect.

I instantiate a token in a function call here:

Token t;
t = Token(tokenAddress);

truffle compile, truffle migrate, and truffle deploy all work fine.

Expected Behavior

truffle publish should publish this package to ethpm

Actual Results

I get the following error:

ParsedContract.sol:64:5: DeclarationError: Identifier not found or not unique.
    Token t;
    ^---^

Environment

• Operating System: OSX
• Truffle version: 4.0.1
• Ethereum client: INFURA (ropsten)
• node version: 8.6.0
• npm version: 5.3.0

We’re getting the same error in the OpenZeppelin repository. It started happening around version 1.4.0.

Does anyone from the Truffle team have any clue as to what could be happening?

@alex-miller-0 @frangio This should be fixed in 4.1.5. Please report back if you continue to see this or have other issues publishing to ethpm.

Thanks!!
