Hi,
Your first problem is that it cannot load library libinet, probably due to setting the path wrong: /..inetmanet/src//libinet.so, perhaps it is ../inetmanet/src/libinet.so?
If the Trapezoid symbol is undefined, the fuzzylite library is not being loaded. You should check the path to the library is correct and make sure you have only one fuzzylite library installed. Also, perhaps the fuzzylite library is not being loaded due to errors loading other libraries like libinet?
