Yep, no problem.
So as to help make your CasaCore.jl maximally useful to others, I'd suggest
trying to get the AptGet provider able to install `libcasacore-dev`
automatically; I'm not sure if we have the ability to request AptGet to
install from a different PPA, but if we don't that's something we can deal
with in a issue on the BinDeps.jl tracker. Once we have that in place,
users should be able to just run Pkg.add("CasaCore"), and BinDeps will take
care of the necessary apt-get magic.
As it stands, BinDeps will attempt to build from source, and because the
source build doesn't set RPATHs properly, the resultant libraries are
unusable because the linker doesn't know to look in the proper directories
for the other libraries. We should also pass the proper linker flags to
the build scripts to get the from source builds to work properly.
Something along the lines of setting LDFLAGS to
"-Wl,rpath,$(joinpath(depsdir,"usr","lib"))"should do the trick, I believe.
