`libLLVM.so.20.1: Shared object "libxml2.so.2" not found`

[hellium6]

$ zig-master version
/usr/pkg/llvm20/lib/libLLVM.so.20.1: Shared object "libxml2.so.2" not found

Probably got broken after an upgrade:

$ ls /var/db/pkgin/cache/libxml2*
/var/db/pkgin/cache/libxml2-2.14.4.tgz
$ pkgin se libxml2 | head -1
libxml2-2.14.4 =     XML parser library from the GNOME project
$ pkgin pc libxml2 | grep \.so
/usr/pkg/lib/libxml2.so
/usr/pkg/lib/libxml2.so.16
/usr/pkg/lib/libxml2.so.16.0.4

It can be solved with something like:

$ cd /usr/pkgsrc/lang/llvm20
$ make clean
$ make update

The above example is for llvm20.

For zig-master it should be repeated for lang/clang20, devel/lld20 and lang/zig-master. "v20250808" release has package files that are linked against latest libxml2.so

The issue also affects other zig versions.

$ zig-0.13.0 version
/usr/pkg/llvm18/lib/libLLVM.so.18.1: Shared object "libxml2.so.2" not found
$ zig-0.14.0 version
/usr/pkg/llvm19/lib/libLLVM.so.19.1: Shared object "libxml2.so.2" not found

The solution should be similar. For example, for zig-0.14.0, make clean, then make update for lang/llvm19, lang/clang19, devel/lld19 and lang/zig-0.14.0. For now, binary packages linked as such for other than zig-master and deps are not available and will have to be regenerated manually.
