安装chmsee 0.9.5检测不通过?

Master

./configure时提示:
checking for libgtkhtml-3.1 >= 3.1.8... Package libgtkhtml-3.1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgtkhtml-3.1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgtkhtml-3.1' found

configure: error: Library requirements (libgtkhtml-3.1 >= 3.1.8) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
我特地emerge libgtkhtml, libgtkhtml的版本是3.6.1,然后重新再来,还是那样.
是不是在gentoo下,PKG_CONFIG_PATH有问题?还是库文件版本太高了?
