The issue with getting the 'Bot name is already in use' message may be a case sensitivity thing on Linux.

The query that is being used to check if the name is available is:

SELECT COUNT(id) FROM vwbotcharactermobs WHERE name LIKE '%s'

But the view name is actually mixed case:

CREATE VIEW `vwBotCharacterMobs` AS ...

You could try changing the query on line 928 in bot.cpp to:

SELECT COUNT(id) FROM vwBotCharacterMobs WHERE name LIKE '%s'

and recompiling.
