Se estiver utilizando Ubuntu (como eu) basta instalar os pacotes do texlive:
apt-get install -y libpoppler2 preview-latex-style tcl8.4 tetex-bin tetex-extra tex-common texlive texlive-base-bin texlive-bibtex-extra texlive-common texlive-doc-base texlive-font-utils texlive-fonts-extra texlive-fonts-recommended texlive-generic-recommended texlive-lang-latin texlive-lang-other texlive-lang-portuguese texlive-latex-base texlive-latex-extra texlive-latex-recommended texlive-math-extra texlive-pictures texlive-pstricks texlive-publishers
E o abntex.
Basta utilizar o comando make. :)
