fink update was failing with the following error about head missing a -n option:
cc1plus: warning: "-Wbad-function-cast" is valid for C/ObjC but not for C++ cursesfile=`echo "#include <curses.h>" | \ gcc-3.3 -E - | grep "curses.h" | head -n 1 | \ sed -e "s/^[^"]*"//; s/".*$//"`; \ if [ "$cursesfile" = "" ]; then echo "can"t find curses file"; exit 1; fi; \ perl /sw/src/dpkg-1.10.21-215/dpkg-1.10.21/dselect/mkcurkeys.pl keyoverride $cursesfile > curkeys.h Unknown option: n Usage: head [-options] <url>... -m <method> use method for the request (default is "HEAD") -f make request even if head believes method is illegal -b <base> Use the specified URL as base -t <timeout> Set timeout value -i <time> Set the If-Modified-Since header on the request -c <conttype> use this content-type for POST, PUT, CHECKIN -a Use text mode for content I/O -p <proxyurl> use this as a proxy -P don"t load proxy settings from environment -H <header> send this HTTP header (you can specify several) -u Display method and URL before any response -U Display request headers (implies -u) -s Display response status code -S Display response status chain -e Display response headers -d Do not display content -o <format> Process HTML content in various ways -v Show program version -h Print this message -x Extra debugging output can"t find curses file
It turns out that the issue is that when you install perl LWP it installs HEAD, GET and POST into /usr/bin. Mac OSX uses HFS+ which is case insensitive - this then overwrites the normal head utility.
I moved the HEAD/GET/POST utilities to /usr/local/bin and grabbed the head utility from a different mac box - this solved the problem.
