问题解决：

其中有一句 
src/pycurl.c:61:4: error: #error "Need libcurl version 7.19.0 or greater to compile pycurl."

提示说libcurl 版本太低... 
root@localhost pycurl-7.19.0]# curl --version 
curl 7.15.5 (x86_64-redhat-linux-gnu) libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5 
Protocols: tftp ftp telnet dict ldap http file https ftps 
Features: GSS-Negotiate IDN IPv6 Largefile NTLM SSL libz 
果然7.15.5小于 7.19 
wget http://curl.haxx.se/download/curl-7.21.4.tar.gz 
.configure ＆＆make && make install

 

下面继续问题 
[root@localhost pycurl-7.19.0]# python

这问题因为机器是64的.所以找不到.
