Forgot to tell about the need to make css/scanner.c on Linux and copy it back as re2c wants gcc4.

+  RE2C
+------
+
+  BeOS doesn't come with the re2c lexer. Unfortunately it requires gcc4 
+  currently, so it cannot be built on BeOS. It might be possible on gcc4 built 
+  Haiku.
+  The workaround is currently to generate the scanner.c file from Linux, and 
+  copy it back to the source tree. Touching it in the future will make sure 
+  make won't try to rebuild it.
