Yes. There are shell functions defined that should not be present in  
a non-interactive environment or in one in which the environment  
variable TERM is either not set or has the value "dumb." The /sw  
components in PATH come indeed from LaTeXiT: it takes care that TeX  
installations from Fink or MacPorts are found even when the user made  
omissions.

I presume the extra BASH stuff is from ~/.bashrc. There you could try  
this that I use (although a tcsh user and copied from somewhere, so  
that prompt (or window title line) handling in xterm or for root is  
not perfect):

case $TERM in
     dumb|eterm)
         # no color on the dummy terminal
         # I should dig up a dummy terminal and test this
         ;;
     "xterm"|"vt100"|"color-xterm"|"xterm-color"|*)
         if [ -n "$TERM_PROGRAM" ]; then
# some prompt tweaking

Apple's Terminal sets TERM_PROGRAM for which I prepare a lot. The  
statement

	case $TERM in

is true when TERM is set, i.e., usually in some interactive session.  
So the stuff following won't be executed at all in LaTeXiT. Before  
the last

	;;

statement you could put all those functions and aliases and other  
stuff that makes an interactive session – in xterm or in Terminal –  
prolific – and useless for non-interactive use as with LaTeXit.
