Ugly LaTeX gerou PDF no OS X

Question

Eu tenho um livro que estou escrevendo no TeX, o que é legal, mas só recentemente percebi o quão feia minha exportação local do TeX para PDF parece:

Para referência, o meu está à esquerda, e uma caixa aleatória do Linux à qual eu tenho acesso gerou o da direita. Veja o quanto mais nítido é? Eu estou meio confuso sobre o porquê disso.

Aqui está a versão do meu local pdflatex :

pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2014)
kpathsea version 6.2.0

e a caixa do Linux:

pdfTeX using libpoppler 3.141592-1.40.3-2.2 (Web2C 7.5.6)

Edit: Acabei de perceber que a caixa do Linux usa libpoppler e usei xpdf . Poderia aquela ser a razão? Como eu mudo?
