IconLoader.cc:20: error: ‘getenv’ was not declared in this scope
make: *** [IconLoader.o] Error 1
I also had this problem, here's a fix:
Just replace getenv("HOME"); with the path to your home directory e.g.: "/home/user"
You have to do that in about three files and compile then, should work.
If someone has problems using the wbar in dual screen mode i'll have a fix too
