I have a clean install of gwTeX and it just has lm.map.

If I pdflatex the minimal example I am told that lmmi10 and
lmex10 are missing. Locate in terminal tells the .pfb's are
present so there has to be a reason why they are not being used.

So I checked lm.map, and indeed these fonts do not have an entry.
I downloaded the lm.map from CTAN and it is 2K larger than the
one in gwTeX. Having replaced the gwTeX lm.map by the one on
CTAN and rerun the Configure stage of i-Installer, the problem
goes away for me.
