Comment (by trommler):

 Replying to [comment:11 nomeata]:
 > > To load a static library we use the RTS linker and the RTS linker
 needs to load dependent C libraries explicitly. Unfortunately we cannot
 assume that the C library with a specific version is installed. So the RTS
 linker looks for the unversioned library and tries to load that.

 one version and run against another version of the library?
 You don't have to recompile for say a security fix in a shared library.

 The official GHC binaries are build against a certain version of the
 standard C library (libc) but generally work with a newer libc as long as
 it is binary compatible.
