之前按照这篇文章安装vim7.4，因为使用YCM和UltiSnips的缘故。在安装过程中make时，出现如下错误：       

Undefined symbols for architecture x86_64:
"_iconv", referenced from:
_buf_write_bytes in fileio.o
_readfile in fileio.o
_my_iconv_open in mbyte.o
_string_convert_ext in mbyte.o
(maybe you meant: _my_iconv_open)
"_iconv_close", referenced from:
_buf_write in fileio.o
_readfile in fileio.o
_my_iconv_open in mbyte.o
_convert_setup_ext in mbyte.o
"_iconv_open", referenced from:
_my_iconv_open in mbyte.o
(maybe you meant: _my_iconv_open)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
make[1]: *** [vim] Error 1
make: *** [first] Error 2

在configure时，使用如下命令即可

LDFLAGS=-L/usr/lib ./configure --with-features=huge --enable-pythoninterp=yes  --enable-cscope --enable-fontset --enable-perlinterp --enable-rubyinterp --with-python-config-dir=/usr/lib/python2.6/config --prefix=/opt/local

Mac安装vim7.4
