Clarification on Packaging Guidelines

Actually my question was for a standard shared library package.  This is 
a GTK widget called 'gtkdatabox' which is currently in bugzilla as a 
review request (#196529).  I have a normal package which has 
libgtkdatabox.so.* then the -devel package with the headers, pkgconfig 
files, and .so symlinks.  According to previous responses, since the .so 
files are symlinked the %pre/%postun are not needed.  Maybe it is clear 
but I got confused somewhere in the process.

Thanks,
Eric
