I agree. What about running ldd on <prefix>/lib/plplot-*/cairo.so? Anything differences in this between the two working directories? The drivers are loaded dynamically on demand I think which is why the cairo libraries (for example) aren't explicitly required by the test application. > The only difference I can see in strace is that when I run in /home/ > hbabcock/OpenSource/plplot-working/plplot-CBS-1, the program looks in > this directory first before looking in /usr/lib, however all the > libraries still seem to be found in /usr/lib.
