The problem here is JSC depends on WTF(who would name its library that? it seems the acronym of webkit's template framework). Dynamic loader has difficulty to resolve this symbol in WTF. we need to teach dynamic laoder to get from what you built

one way to around arount it. ./Tools/Scripts/run-jsc --debug This is equivalence of DYLD_FRAMEWORK_PATH=/Users/xxinliu/Devel/WebKit/WebKitBuild/Debug /Users/xxinliu/Devel/WebKit/WebKitBuild/Debug/jsc --useDollarVM=1
