rebuild not giving same results

Should I not be able to do makepkg -s with a package loaded with abs and get exactly the same binary functionality as a package downloaded using pacman -S?

My case is that audacity has recently broken and other postings point to changes in wxgtk2.8 from warnings to fatal errors. So, I used abs to get the source and before fiddling with it at all, tried to re-build and install. This all worked, but now the audacity dies silently rather than spitting out some error messages first - clearly my re-built wxgtk libraries are not the same as the ones from extra yet they both say they are version  2.8.12.1-3

Have I misunderstood, and if not, what else can I try?

No.

Those warnings are meaningless, which is why it's still dying.

[SOLVED] audacity is not crashing because of wxgtk incompatibility. Solution is to remove old ~/.audacity-data.

However, I'd still love to understand why re-building an unmodified package gave different results to that produced by the pre-compiled version. I can see that I might have a newer version of gcc etc than the packager, so the binary files might not be totally identical, but surely functionality should be identical?

Re: rebuild not giving same results

You have different packages on your system than the build root did.
