centos6.2 upgrade python2.7 _hashlib and _ssl build failed and make [Modules/_ssl.o] Error 1
<p>I want to upgrade default python2.6.6 to python2.7 from source code, I installed:</p>

<pre><code>yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel
</code></pre>

<p>but _hashlib and _ssl is failed to build.</p>

<p>my openssl is installed:</p>

<pre><code>whereis openssl
openssl: /usr/bin/openssl /usr/lib/openssl /usr/lib64/openssl /usr/local/bin/openssl /usr/include/openssl /usr/share/man/man1/openssl.1ssl.gz
</code></pre>

<p>And I uncomment the Module/Setup about ssl config like this:</p>

<pre><code># Socket module helper for socket(2)
_socket socketmodule.c timemodule.c

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto
</code></pre>

<p>then </p>

<pre><code>./configure --prefix=/usr/local/python27/ --enable-shared
make
</code></pre>

<p>it has errors:</p>

<p>If dont use ssl, the make is not this error, it shows:</p>

<pre><code>Python build finished, but the necessary bits to build these modules were not found:
bsddb185           dl                 imageop         
sunaudiodev                                           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


Failed to build these modules:

<p>I want to know how to fix this, Thanks.                   </p>
