Did you delete all the directories that were created with nph-build.cgi via your web browser BEFORE executing the script via telnet? If not...first delete all the directories (you can do this via FTP), then execute the nph-build.cgi.

BTW: I really don't think that telnet is the ultimate solution since my building process is killed after building two categories (with 110 subcategories) and 1000 links. I believe that the sub build_category_pages needs to be hacked to complete the build process.
