Latex - missing `zref-abspage.sty'

I'm trying to use a template (Eisvogel) with pandoc to convert a markdown file to a specifically formatted PDF.

The command fails with:

Code:Error producing PDF.
! LaTeX Error: File `zref-abspage.sty' not found.The template documentation mentions that these errors come from an incomplete Latex installation:

Quote:

Eisvogel requires a full texlive distribution that can be installed by running apt-get install texlive-full in the terminal. Because texlive-full is very large (about 5 Gigabytes) you can also install the smaller texlive bundles and add any missing packages manually. A smaller texlive bundle is texlive-latex-extra. With texlive-latex-extra you also need to install these packages manually: adjustbox babel-german background bidi collectbox csquotes everypage filehook footmisc footnotebackref framed fvextra letltxmacro ly1 mdframed mweights needspace pagecolor sourcecodepro sourcesanspro titling ucharcat ulem unicode-math upquote xecjk xurl zref.

I have texlive-extra installed and updated from SBo (I'm using 15.0). I'm assuming once I fix the zref package error, I'll run into others from the list above. Is there a "Slackware" way of easily finding and installing these? I found a "zref" package, but it contains no .sty files.

I found this thread: https://www.linuxquestions.org/quest...-a-4175725348/

...but have not been able to parse a useful answer from it for my specific problem. TIA
