thanks for pointing me to those issues. they are instructive as of the
dilema on which binary to run, and against which server.

i will implement those calls this way, the moment after the libpostgis
and binaries are installed.

mind you, the difference between the older libpostgis package and the
present one, relays in the low level support for concomitently installed
postgresql of multiple versions, both at build time and at runtime.

there still are a few issues, and you will be kept updated to be able to
test with latest versions.

best regards,
