libMagickCore.so.5 and libcfitsio.so.3 missing on upgrade to Ubuntu 15.04

When trying to use sharp on Ubuntu 15.04, I get errors about the absence of libMagickCore.so.5 and libcfitsio.so.3 (maybe because libmagickcore5 isn’t available in 15.04?)

Anyway, I was only able to get it working by linking to the libraries like so:

cd /usr/lib/x86_64-linux-gnu
sudo ln -sf libMagickCore-6.Q16.so libMagickCore.so.5
sudo ln -sf libcfitsio.so libcfitsio.so.3

yeah, fixing $PKG_CONFIG_PATH was the solution.

i managed it to crack that problem myself with this:

there is definitely a mess with the pkg configuration …
