Cabal means the curl C library, which must be installed by either the packages libcurl4-openssl-dev or libcurl4-gnutls-dev. If a situation like this happens again, you can search for candidate packages with: $ apt-cache search lib curl dev collectd-core - statistics collection and monitoring daemon (core system) libcurl4-gnutls-dev - Development files and documentation for libcurl (GnuTLS) libcurl4-openssl-dev - Development files and documentation for libcurl (OpenSSL) devscripts - scripts to make the life of a Debian Package maintainer easier libflickcurl-dev - C library for accessing the Flickr API - development files libghc6-curl-dev - GHC 6 libraries for the libcurl Haskell bindings liblua5.1-curl-dev - libcURL development files for the Lua language version 5.1 liblua5.1-curl0 - libcURL bindings for the Lua language version 5.1 libwww-curl-perl - Perl bindings to libcurl libcurl-ocaml-dev - OCaml libcurl bindings (Development package) python-pycurl-dbg - Python bindings to libcurl (debug extension) python-pycurl - Python bindings to libcurl tclcurl - Tcl bindings to libcurl php5-curl - CURL module for php5 Or, even better, use the aptitude interface and search (with /) for "lib curl dev", which will lead you directly to the right package in this case.

Just as a general thing, almost all Linux distributions separate the runtime and development components of any package; if you need developer libraries, you need to install the -dev / -devel package corresponding to the runtime package. (I have never been convinced this actually accomplishes anything other than causing lots of support questions; any space that might be saved by not installing a bunhc of tiny headers and a symlink or two is then lost by having several GB of Gnome libraries in a basic install.....) -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
