What kind of support problems did you have? I found the opposite. It was possible to get such a good level of programmer from the community I was better off having found them letting them go work for the D Foundation on rebuilding compile time function execution. Libraries - meaning a bit more work to have idiomatic style use, but if you write D as C, that's usually okay - and wrapping is a one time cost.
I would say that I have found it to be more of a problem on Windows. That'd because the general C/C++ package management solution on Windows is quite... Old fashioned, and that's not always a D specific problem.
