After a new installation -- apparently successful, the "create-administrator" command is not found.  I am using the correct directory.

Would appreciate tips on how to diagnose & fix problem and/or find & use the command. 

Failing that, can I simply insert  rows into the database directly?  Seems that "eperson" and "epersongroup2eperson" would be all that require entries, right?

Environment:
DSpace 4.2
openjdk-7-jdk
Apache Maven 3.2.2
Apache Ant 1.9.3
tomcat7
postgresql 9.3+154
Linux Mint 17 Cinnamon 64-bit (kernel 3.13 / Ubuntu 14.04)

Thanks.
