After updating ICU to 5.5 (in Debian unstable), now, harfbuzz cannot be compiled. This is because of the change of the signature of the virtual function, getFontTable. It seems that updating harfbuzz to the latest version solves this issue.

Comment on attachment 262828 [details] Patch Currently, I still cannot build WebKitGTK+ on debian unstable because Mesa also raises some linking errors with LLVM. But at least, harfbuzz phase was OK.
