configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables PCRE_CFLAGS
and PCRE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

解决方法：

sudo apt-get install xsltproc  rst2man libncurses5-dev

Consider adjusting the PKG_CONFIG_PATH environment variable if you 
installed software in a non-standard prefix. 

Alternatively, you may set the environment variables PCRE_CFLAGS 
and PCRE_LIBS to avoid the need to call pkg-config. 
See the pkg-config man page for more details. 

解决方法：

sudo apt-get install libpcre3-dev

export PKG_CONFIG_PATH=/usr/local/lib

再重新编译即可。
