As you can see, this is with the bad package, the symlinks are very
broken (colored in red).

Title:
  [SRU] calf.lv2: incorrect symlinks

Status in calf package in Ubuntu:
  Fix Released
Status in calf source package in Plucky:
  Fix Committed
Status in calf source package in Questing:
  Fix Released

Bug description:
  [Impact]

  Users are unable to load audio plugins included with the package.

  Easyeffects can not open some of the calf related .so files because
  they point to a /build path.

  Additionally, other plugin hosts such as Carla cannot even use them
  since they're incorrect.

  [Test Case]

  * install calf-plugins
  * do the following to check the symlinks:

  $ ls -la /usr/lib/lv2/calf.lv2/

  Expected: no symlink should point to a path starting with /build

  Additionally, install Carla or Easyeffects and verify at least one
  plugin can be loaded and used there.

  [What could go wrong]

  calf is relying on a new build system than before (0.90.3 in oracular)
  and has a new maintainer, so anything is possible. The bad symlinks
  are in themselves a regression, so it is certainly possible other
  regressions are found within. However, fixing the installation
  directories is certainly a step in the right direction.

  [Other information]

  This is fixed in two commits culimating in a point-release:
  https://github.com/calf-studio-
  gear/calf/commit/37a34fec707aa520e5fdc151e5c449e258e11970 and
  https://github.com/calf-studio-
  gear/calf/commit/fc4605d965cc8c1c32e5d42f7518445740f233d9.

  [Original Bug Report]

  Easyeffects can not open some of the calf related .so files because
  they point to a /build path.
