I have both ldc and gdc install on my OpenSUSE tumbleweed machine.
Without ldc-runtime-devel, gdc is able to compile successfully.

However, after installing ldc-runtime-devel, gdc fails to compile a "hello world" because it tries to use the phobos library provided by ldc.
gdc installs its library at /usr/lib64/gcc/x86_64-suse-linux/13/include/d/
ldc installs its library at /usr/include/d
gdc -v source/app.d shows,

How may I fix it? I tried to use "-I" and "-B" option, but to no avail.
