Library: libjpeg
SONAME: libjpeg.so.62
So if you want to build LSB packages, you need libjpeg62-dev.

The conflict is needed because they both install the file
/usr/include/jpeglib.h.

I am not sure what you means, but I proposed to do thing differently:
to rename libjpeg62-dev to libjpeg6b-dev and to have libjpeg8-dev
provide libjpeg62-dev, but this was not accepted because
that would mean that packages build-depending on libjpeg-dev and
libjpeg62-dev had to transition at the same time. So libjpeg8-dev
does not provide libjpeg62-dev and that lead to the current situation which
require to fix packages that _Depends_ on libjpeg62-dev first.
