Comment 4 for bug 13327

jaldhar: I'm cc'ing you since you've made the last couple of
versions/uploads and might have a clue about finding the missing
is13194-bn.cset file.

Not knowing any Bengali whatsoever, I don't know if this is helpful, but
ftp://ftp.gnu.org/gnu/aspell/dict/bn/ has a tarball that contains
u-beng.cmap and u-beng.cset that can be copied to the aspell-bn source
directory as is13194-bn.cmap and is13194-bn.cset (the latter may need to
be edited to contain "= is13194-bn" instead of "= u-beng" at the top).
With these files, the package will build, but I don't know if it works.

(Hoping to be helpful here, sorry if I'm on a wild goose chase.)
