Oh, what a joy discovering that TexLive packages in CentOS 7 are bugged or crippled beyond any reasonable amount!
Furthermore TeXlive in distros like CentOS 7 is crippled since they don’t offer the TeXlive Manager called tlmgr. So updating packages is a pain, since it has to be done manually, which is far from being trouble-free — newer versions of LaTeX packages could depend on newer versions of other LaTeX packages and so on and so on.And at last, TeXlive is just a snapshot of CTAN, at least regarding LaTeX packages and lots of other stuff. So having a possibility to update sounds like a very good idea to me.So as conclusion: Just forget the TeXlive packages from CentOS 7. Install the regular TeXlive. [5] As prerequisites you need to install the CentOS packages “perl-Tk” and “perl-Digest-MD5”, afterwards the installation should be pain-free

Quite frankly I consider quite a failure to rely on the TexLive specific installer
