The issue is one of > attempting to use a *linux* shared library in a native application. Linux uses the same linker (GNU ld). Fixing the linker will have the same effect on Linux as it will have on FreeBSD and hence will prevent unnecessary dependencies in Linux libraries to Linux libraries and thus remove the need to patch ELF files in the long run. -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
