You have complete record of everything I did in the log. I did nothing else.

??? Of course my package is building from the source. There are no
additional patches or sources in the package, if that's what you mean.

No, of course not -- that's -devel like "use for development", not
"development version"; most Linux distributions have separate packages
for  normal use (for libraries they contain usually the library itself
and documentation) and for development use (with header files, etc.).
Therefore, normal users install just basic packages and only if you need
to develop based on the package, you need to install -devel packages.

Thanks for any suggestions,
