=====
The libpqxx packages need to be rebuilt with GCC-5 and
may also require either a package rename or a soversion bump.
>From the above link:
"If the library is incompatible, rename the package,
append 'v5' to the name of the package (e.g. libfoo2 -> libfoo2v5).
Such a change can be avoided, if you have a soversion bump
and you upload this version instead of the renamed package."
