libc0.1 and usrmerge

Hi all, I've recently noticed that all of my packages are unbuildable 
on the kfreebsd ports. This seems to be because usrmerge conflicts with 
glibc versions older than 2.35-4; taking mbedtls' buildd status page[1] 
as an example:

    usrmerge conflicts with:
    - libc0.1:kfreebsd-amd64 (< 2.35-4)

Having a look at glibc's buildd status page[2], the same dependency 
problem is shown. Does this mean that glibc can't be built on kfreebsd 
because glibc itself is too old?

How can this be fixed? Should usrmerge's Conflicts be adjusted?

Thank you for your work on the BSD ports.
