[LAU] lv2core any alternative ?

Hi, Having installed Lubuntu 18.04.3 64-bit on my old Laptop, I realized that the calf-plugins from the distro's repositories were perhaps quite old (0.60) while the latest available from calfpluginstudio are 0.90. I am thinking of building from source (unless someone has a good PPA), but building from source requires the package 'lv2core' to be installed, where-as it seems that Ubuntu 18.04.3 no longer has this package (which is supposed to be a 'dummy' package). Any thoughts on whether there is an alternative dummy package, or if I could ignore it and proceed with the build ? thanks, BD <http://twitter.com/edgeliving>
