Hi all,

In freesurfer-7.4.1, the nu_correct command gives this error:

``` Can't locate Sys/Hostname.pm in @INC (you may need to install the Sys::Hostname module) (@INC contains: /software/rocky9/freesurfer-7.4.1/mni/share/perl5 /usr/local/lib64/perl5/5.32 /usr/local/share/perl5/5.32 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at /software/rocky9/freesurfer-7.4.1/mni/share/perl5/MNI/MiscUtilities.pm line 36.

We are in Redhat 9 OS. Is this expected? Could you recommend a solution?
