(I don't know if this bug may be related to bug #892 by drobbins) when aspell-0.32.6 is merged (which is the highest unmasked version as far as I can see) it works with pspell-0.11.2 but not with pspell-0.12.2-r1 which is the latest unmasked. ldd /usr/bin/aspell reveals that several libpspell libs are missing (mostly .so.3 and .so.4) but symlinks to the proviede .so.4 & higher libs do NOT fix the problem on my machine (at least not from within emacs - an error message & a hanging process result)
cc'ing seemant as he seems to be interested in helping get aspell straightened out also.
