'Main' is the name of the default package.  That is, when you don't give
a -package-name flag, the module being compiled is assumed to belong to
package 'Main'.  The 'Main' package usually contains the 'Main' module.

I can't tell exactly what's gone wrong, but perhaps you managed to
compile a module without a -package-name flag somewhere?
