ArchLinux libassuan upgrade problem (related to: libassuan 3.0.0 bumped the soname without bumping the symbol versioning)

[Bernhard Reiter]

Hi,

got a problem report via the fediverse. 

== Background

libassuan-3.0.0.tar.bz2	came on 2024-06-18
and six days later there is 3.0.1 as quick-release upgrading the soname
to what it should have been (see citation below).

== Problem description

Arch Linux packaged the 3.0.0 release and has problems upgrading from it now.
Here is the problem description:

"
with the release of 3.0.0 the soname changed from libassuan.so.0 to 
libassuan.so.9.
Only with 3.0.1 the symbols have been changed from LIBASSUAN_1.0 to 
LIBASSUAN_2.0 (which is the ABI breaking change that the soname change is 
supposed to indicate).

Since #pacman requires the library transitively via #gpgme, there now is no 
clean way to upgrade this without patching all consumers in some intermediate 
step. (The staging build environment would otherwise have a broken pacman and 
thus not be functional).

We are stuck on 3.0.0 because our packaging environment now requires 
libassuan.so.9 with symbols LIBASSUAN_1.0.
"

Does anybody have some ideas how to solve this for Arch Linux in an elegant 
and efficiant way?

Best Regards,
Bernhard
