fai-client as RPM, depends "libgraph-perl"

[Schulz, Reiner]

Hi,

i try to "alien" the fai-client deb to rpm for our RHEL Systems.

There ist a depend for libgraph-perl  which provides "perl::Graph::Directed"

I only found this git commit for that:
commit 993b6f1b5f09fdc788eb55777532f5e566238ae7
with note: " Also build-depend on libgraph-perl, so the compile check succeeds. 
"

For what is this used?
AND it is possible to remove the dependency?

libgraph-perl and libfile-lchown-perl are not available for RHEL or EPEL
