I'm dense. Would you mind pointing out the part of the Pd-l2ork build
systemwhere Ivica is linking the wrong way, and maybe explain what to replace
thatcode with in order to leverage this "well established system" such that a
binaryfrom 2013 works on Jessie today?
Thanks,Jonathan

i would say that Debian has a pretty well established system to avoid
breakage of applications due to library incompatibilities.
part of this scheme is to rename library packages (e.g. "libMagick++4"
vs "libMagick++5") if and only if the two libraries are binary incompatible.
usually this means that some previously exported symbols have vanished
in the newer version.
a specific application might not use those symbols at all and would thus
not be affected by the incompatibility.
but using symlinks (system-wide!) is certainly the right approach to
break your system, and thus should be avoided.
there are two solutions for this problem:
- ship all dependencies (the w32 and OSX way)
- link against the proper libraries (the linux distro way)
