It's really hard to say man, there are so many variables. If you didn't gain muscle, then obviously your program had some flaws. Everyone can gain muscle, even skinny fucks.
With that said, 6 months is a drop in the bucket. I would be ECSTATIC to gain 5lbs of actual muscle in 6 months.
Most people over-estimate what they can accomplish in a year, and underestimate what they can do in a decade.
If you want to talk training and nutrition, PM me and I'll be happy to work with you a little on getting closer to your goals.
