> Hello,

imlib2-config was removed in imlib2 version 1.7.5 from 2021. imlib2 is
now at version 1.12.4. Please use pkg-config instead.

The "can't find loaders" problem you see may happen if the perl module
dlopens libImlib2.so with RTLD_LOCAL instead of RTLD_GLOBAL.
A change was introduced in imlib2 version 1.12.4 that requires
libImlib2.so to be loaded with RTLD_GLOBAL.
