I implemented (revision 10171) exactly what is currently done for qt.so. The result works for me, and I think it will also work for your situation without issues. There are some minor theoretical issues (see the commit message) on the resulting rpath order for both qt.so and libplplotqtd.so if a system location such as /usr/lib is used for either PLplot or QT4. I believe there is a potential way out of these issues to obtain a perfect solution. However, it is a little complicated (separate find_library command when figuring out rpath). Furthermore, I don't think the issues will be of concern for the vast majority of users. Thus, I haven't bothered with the "perfect" solution here. Alan __________________________ Alan W.
