[arch-haskell] lhs2tex broken

[Wei Hu]

After the gmp upgrade, I had to upgrade this package too. It failed to
find polycode.fmt when processing .lhs files:

lhs2TeX: user error (File `polycode.fmt' not found in search path:
.
/home/wh5a/lhs2tex-1.15
/home/wh5a/lhs2tex

However, I do have /usr/share/lhs2tex-1.15/polycode.fmt. Any ideas?
