ubuntu12.04下编译安装freetype出现如下错误信息：
configure: creating ./config.status config.status: creating unix-cc.mk config.status: creating unix-def.mk config.status: creating freetype-config config.status: creating freetype2.pc config.status: creating ftconfig.h freetype build system -- automatic system detection the following settings are used: platform unix compiler cc configuration directory ./builds/unix configuration rules ./builds/unix/unix.mk if this does not correspond to your system or settings please remove the file `config.mk' from this directory then read the install file for help. otherwise, simply type `make' again to build the library, or `make refdoc' to build the api reference (the latter needs python). make: nothing to be done for `unix'.
