usetex failure in latex documents
When I use matplotlib's internal tex (rcParams['text.useTex']=False), the postscript files generated cause errors that look like this when you try to ps2pdf them:
They will not open in MacOS's Preview.app either.
Solution: Make figures with rcParams['text.useTex'] = True
ps2pdf h2co_pilot.ps

RATRAN on Mac OS X
Mac OS X doesn't like the defaults built in to RATRAN. It died unhappily with errors like:
and
In order to get it to run, I had to do the following:
ld_classic: can't locate file for: -lcrt0.o
and
ld: warning: in /usr/local/lib//libcfitsio.a, file is not of required architecture
In order to get it to run, I had to do the following:
- Install CFITSIO with
CFLAGS="-arch x86_64 -arch i386 -g -O2"
to /usr/local/lib - Edit the sky/Makefile OPT variable (line 23) to read:
OPT = -I. -O2 -fno-automatic -arch x86_64
export RATRAN=/path/to/Ratran
export RATRANRUN=/path/to/Ratran/run
