zlib module missing

Question

I have compiled and installed python 2.7 on my ubuntu lucid.
But I am unable to install setuptools for python 2.7 because the data decompression module zlib is not present. This is the exact error:

 Traceback (most recent call last):
  File "setup.py", line 94, in <module>
    scripts = scripts,
  File "/usr/local/lib/python2.7/distutils/core.py", line 152, in setup
    dist.run_commands()
  File "/usr/local/lib/python2.7/distutils/dist.py", line 953, in run_commands
    self.run_command(cmd)
  File "/usr/local/lib/python2.7/distutils/dist.py", line 972, in run_command
    cmd_obj.run()
  File "/home/rohan/setuptools-0.6c11/setuptools/command/install.py", line 76, in run
    self.do_egg_install()
  File "/home/rohan/setuptools-0.6c11/setuptools/command/install.py", line 96, in do_egg_install
    self.run_command('bdist_egg')
  File "/usr/local/lib/python2.7/distutils/cmd.py", line 326, in run_command
    self.distribution.run_command(command)
  File "/usr/local/lib/python2.7/distutils/dist.py", line 972, in run_command
    cmd_obj.run()
  File "/home/rohan/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 236, in run
    dry_run=self.dry_run, mode=self.gen_header())
  File "/home/rohan/setuptools-0.6c11/setuptools/command/bdist_egg.py", line 527, in make_zipfile
    z = zipfile.ZipFile(zip_filename, mode, compression=compression)
  File "/usr/local/lib/python2.7/zipfile.py", line 651, in __init__
    "Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module

Also when i try to use setuptools 2.7 .egg, it gives this error:

Traceback (most recent call last):
File "<string>", line 1, in <module>
zipimport.ZipImportError: can't decompress data; zlib not available

You forgot to install zlib1g-dev before building Python.
