Comment(by bugs at capelis.dj):

 Actually this one is substantially better as it will try and find the
 actual configuration file instead of just assuming it's at the standard
 prefix.  The advantage to this being that we can actually try and actually
 respect prefixes instead of just pretending to. :)

 {{{
 #!/bin/bash
 IFS=":"
 for dir in $PATH; do
 if [ -e `echo ${dir}/etc/macports/macports.conf | sed s/\\\/bin//` ]; then
 CONF=`echo ${dir}/etc/macports/macports.conf | sed s/\\\/bin//`
 fi
 done
 if [ ! -e ${CONF} ]; then
 echo "No configuration for macports found"
 exit
 fi
 PREFIX=`cat ${CONF} | grep ^prefix | cut -f 2- | xargs -n 1 echo`

 if [[ $1 == "--libs" ]]; then
 echo "-L${PREFIX}/lib -ltasn1"
 fi
 if [[ $1 == "--cflags" ]]; then
 echo "-I${PREFIX}/include"
 fi
 if [[ $1 == "--version" ]]; then
 echo "1.6"
 fi
 }}}
