Dear Cabal developers More woe: simonpj@MSRC-3645512:~$ cabal install lhs2tex Resolving dependencies... Up to date cabal: installdir is not defined. Set it in your cabal config file or use --installdir=<path> In the olden days, didn't cabal install by default in ~/.cabal/bin? Never mind, let's do what it asks: simonpj@MSRC-3645512:~$ cabal install lhs2tex --installdir=/usr/bin Resolving dependencies... Up to date Symlinking 'lhs2TeX' /usr/bin/lhs2TeX: createSymbolicLink: permission denied (Permission denied) Darn: I need to be super-user. Fine: simonpj@MSRC-3645512:~$ sudo cabal install lhs2tex --installdir=/usr/bin [sudo] password for simonpj: cabal: unrecognized 'install' option `--installdir=/usr/bin' OK _now_ I really am stumped. It asked me to provide that option, and now it says it's unrecognised. (This is in a bash shell running in emacs, if it makes a difference.) What next? Thanks Simon
