Question: Error, (in march) archive data file could not be created

I'm working with saving procedures to repositories for the first time.  I have been using the following documentations as a guide:
http://www.maplesoft.com/support/help/Maple/view.aspx?path=libname
http://www.maplesoft.com/support/help/Maple/view.aspx?path=repository%2fmanagement

Anyhow, when I run this code at the start of my program:


restart;
savelibname :="/Users/ryderbergerud/Documents/School/year4/Summer/Research/myLib";
march('create',"/Users/ryderbergerud/Documents/School/year4/Summer/Research/myLib/myLib.mla");
libname:=libname, "/Users/ryderbergerud/Documents/School/year4/Summer/Research/myLib"; 

However, using march gives me an error.
Error, (in march) archive data file could not be created

The documentation also mentions I need not use march as the saveLib command will automatically will create a repository (the mla file?)
"A repository is automatically created when you save expressions via the LibraryTools[Save] command."

however when I run
savelib('TransM');

I get:
Error, could not open `/Users/ryderbergerud/Documents/School/year4/Summer/Research//TransM.m` for writing 

Thanks.
