This appears to be caused by brianmario/yajl-ruby@fa3c9a6 which set the visibility of libyajl symbols to hidden. This means that heap_dump can't compile against yajl-ruby 1.2.0 or newer.

@jhoblitt, heapdump uses yajl that is linked into yajl-ruby, not the system one, as @Sharpie pointed out - here comes the moment when it can no longer.
Time permitting i'll revise build configuration to link to system libyajl when yajl-ruby is not compatible.
Meanwhile - try adding an older yajl-ruby to your gemfile/gemset

@Vasfed It turns out the problem was that yajl-ruby 1.2.0 marks all of the symbols in yajl.so as non-visible. Downgrading to 1.1.0 appears to work (in the sense, it at least compiles). Would you like a PR to update the gemspec?

Vasfed added a commit that referenced this issue May 29, 2014
@Vasfed
yajl-ruby 1.2 hides symbols thus not compatible, use 1.1 for now, refs …
