You'd either use LD_LIBRARY_PATH, which is going to be a bit brittle
when a build system or other script depends on using LD_LIBRARY_PATH for
its own purposes, or compile the stuff needing the libraries with
LDFLAGS='-L $HOME/lib/ -Wl,-rpath,$HOME/lib'
Neither option is entirely painless, unfortunately.
In this particular case, it might work better if automake's test binary
magic did use LD_LIBRARY_PATH and *pre*pended the .lib directory, but I
guess it does things differently, either using -rpath or *a*ppending
I guess that the case of LD_LIBRARY_PATH pointing out a different
version of the libraries under test is broken/unsupported, or at least
isn't supported with the Solaris runtime linker.
(I should probably not speculate more on exactly how it fails, but I'd
be happy to hear the precise explanation if someone here really knows
the automake magic involved).
