while the python module in python-pycurl links to lots of different things the rpm doesnt have requires for them. this can result in a non working package if noting else pulls in what is required

rpm should add requires automatically

Comment 1 Panu Matilainen 2010-12-21 04:58:59 UTC

Nope, ldd is just reporting the libraries recursively while rpm only collects the directly linked libraries. Contrast the above with eg

[pmatilai@localhost ~]$ objdump -p /usr/lib64/python2.7/site-packages/pycurl.so|grep NEEDED
  NEEDED               libcurl.so.4
  NEEDED               libpython2.7.so.1.0
  NEEDED               libpthread.so.0
  NEEDED               libc.so.6

Run objdump -p recursively on the above four libraries and everything they link to and you'll get the same list as with ldd.
