Not necessarily. Sometimes the lack of libraries isn't solely because it is the wrong technology, but because it is the wrong community. Language and community are pretty intertwined.

LISP for example is a great technology for a lot of things, but library-wise it suffers because within that community there is a tendency for people to "roll their own" solutions.

Java has tons of libraries, but I'm not sure most people would say it's the right technology for a lot of things. It's generally the right technology for projects that involve lots of developers with mixed levels of ability (before some Java person down votes me for this, consider that Gosling himself made this point back in the mid-90s when he invented the language)
