やってみたけど
configure.ac:30: error: possibly undefined macro: AC_MSG_ERROR
これはconfigure.acのバグというかミスで30行目は

PKG_CHECK_MODULES([CAIRO], [cairo],, [AC_MSG_ERROR([
The cairo library was not found. Either install
the cairo development libraries, or compile without support (--disable-cairo)
])])

マクロを[ ]で囲むなと

PKG_CHECK_MODULES([CAIRO], [cairo],, AC_MSG_ERROR([
(中略)
]))

これで再度autoconfやって./configureやると
configure: error: C compiler cannot create executables
えっ？
もちろんgccは入っています
