Theoretically it would be possible to use something like '%if
"%{l_target -t}" == "..."' inside a *.spec file but this has two
problems: (1) you can compare only against a fixed string (which is
not practical) and (2) it will horribly break the existing FTP service
XML/RDF generator ("openpkg index") parsing tools ("openpkg build") as
they do not understand those types of conditions.
Currently the only possibility I see would be create an option
"with_shared", depend on "libtool" under "with_shared=yes" and use a
'case "%{l_target t}"' inside the %build section in combination with
a wrapping '%if "%{with_shared}" == "yes"' to activate the stuff. Not
elegant, I know. But we are contraint by the RPM features and the
post-processing tools.
But BTW, what is the reason that we need shared libraries for JPEG under
MacOS X?
