Try:
	unset LD_LIBRARY_PATH
	./SqueakVM-2.4c-sparc-solaris-2.5.1 Squeak2.4c.image

If that doesn't work, try:

	LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/openwin/lib
	export LD_LIBRARY_PATH
	./SqueakVM-2.4c-sparc-solaris-2.5.1 Squeak2.4c.image

If you get a "ld.so: stub interception failed" from that, then try:

	LD_LIBRARY_PATH=/lib:/usr/lib:/usr/openwin/lib
	export LD_LIBRARY_PATH
	./SqueakVM-2.4c-sparc-solaris-2.5.1 Squeak2.4c.image

PS: If you have a non-openwin X11 installed then replace "openwin" in the above
    with whatever is needed to get you to the directory containing "libXext.so".

PPS: If you don't have any X installed then give up now. ;-) ;^) ;o)

PPPS: This isn't the first time that Sun's built-in dynamic lib paths have caused
      problems - and it won't be the last.

P^4S: The above examples for for sh/ksh/bash -- [t]csh users should upgrade to a real
      shell before trying any of this.  (Hmm, sorry - it's late; I'm tired. ;-)
