Using xlsread with convertSpreadsheetDates in Compiled MATLAB code

I'm creating a compiled Matlab script for analyzing excel data which contains dates. The handy convertSpreadsheetDates function handle which can be passed into the xlsread function appears to cause an error when running the compiled code from the console:

Error using xlsread (line 247)
Function convertSpreadsheetDates does not exist.
Error in importfile (line 36) % this is the calling line for xlsread()

Error in CallingScript (line 29) % this is the calling line for importfile()

MATLAB:narginout:functionDoesnotExist

I've included importfile.m, convertSpreadsheetDates.m, nargin.m, nargout.m in the Shared resources list of the Build tab. I'm running version R2013a. If it matters, importfile.m is located in a subdirectory. What else can I do? I could convert the dates myself, but if the codes already been written, why duplicate work?

Thanks for the help!

Attached is code sample and test file for anyone who'd like to repro this. Just run this through MCR version 4 (the one that comes with R2013a).

Contacted help support (thanks for the great service!). Version R2013b (MATLAB 8.2) has fixed this issue.
