[yt-users] rockstar loading

[Desika Narayanan]

Hey Britton,

Thanks for this - unfortunately it doesn't seem to work.  I have (for a mac
 os x mavericks):

(yt-x86_64)thundersnow:~ desika$ echo $LD_LIBRARY_PATH
/Users/desika/yt-x86_64/lib:/Users/desika/yt-x86_64/src/yt-hg/yt/analysis_modules/halo_finding/rockstar/:/Users/desika/yt-x86_64/src/rockstar/:/opt/gsl/lib/:

(yt-x86_64)thundersnow:~ desika$ echo $DYLD_LIBRARY_PATH
/Users/desika/yt-x86_64/src/yt-hg/yt/analysis_modules/halo_finding/rockstar/:/desika/yt-x86_64/src/rockstar/

and end up with the same error (re-linked just in case) -
http://paste.yt-project.org/show/5225/

thanks
