Python and bzip2

[lee218llnl]

Python is not building the bz2 module because it is trying to link to the bzip2 package's .a file which was not compiled -fpic. The bzip2 package does build a shared library, but only appears to generate versioned .so files/links, i.e., libbz2.so.1.0 and libbz2.so.1.0.6 and not the generic libbz2.so.

@lee218llnl: would adding the symlink fix this? I could add this to the bzip2 package post-make('install'). If not, then we could build the .a with -fpic but I dunno what other packages that might affect (Mark Miller and I kind of talked about this here)

[lee218llnl]

Todd, I think adding a symlink will suffice. I will work on this.

@lee218llnl @tgamblin The python package doesn't work properly at the moment. Although it "depends" on openssl, bzip2 etc, it doesn't build the modules for them. (If you have the OS openssl-devel package installed then it will). I've been trying to work out why my python wasn't built correctly and found that if the LDFLAGS and CPPFLAGS aren't set correctly, then setup.py won't find the headers and libraries. As these are normally set by the cc wrapper, they don't end up visible to setup.py.

I'm just testing an updated package for python at the moment, (with some updates for python3 as well).

@lee218llnl @tgamblin I've added PR 215 which I think resolves the build issues.
