Linux에서 freetype을 컴파일하고 설치할 때 발생하는 오류 메시지 및 해결 방법

ubuntu12.04에서 freetype을 컴파일하고 설치할 때 다음 오류 메시지가 나타납니다.

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'.
