it is probably not worth trying to patch this any further, rather than
updating it (although there are/were some problems with things it may
depend on) but maybe making some progress will inspire someone else to
take this up.
In particular I tracked down the lossage where it was looking for vala
1.0 and the current vala versions are 0.12 and 0.14. It seems that
what someone optimistically intended at some point to be vala-1.0
(after vala-0.9) ended up released as vala-0.10.
Val(a)IDE is an Integrated Development Environment (IDE) for the
Vala programming language.
