Why remove the sources?  After configuration, they have all the 
information you are asking for.

If it's about saving disk space, most of the bulk in a built package is 
in the resulting binaries.  It's a pretty wasteful process, what with 
the executables duplicating what's in *.o and the convenience libraries, 
plus overhead for any static links, plus debug info...  So, I just say 
'make clean' sometime after 'make install' when I'm sure the package is 
working and I won't need to rebuild it for any reason.  That keeps the 
size of /usr/local/src under control.

If an expanded package still takes up too much space, I "collapse" it:

#!/bin/bash
filename=$1

if [ ! -d "$filename" ] ; then
        echo Sorry, $filename is not a directory.
        exit
fi

tar -cvjf "$filename.tar.bz2" "$filename"

if [ $? -gt 0 ] ; then
        echo Something bad happened while tarring directory.  Exiting.
        exit
fi

echo
echo Calculating space savings...
typeset -i original=`du -sk "$filename" |cut -f 1`
typeset -i packed=`du -sk "$filename".tar.bz2 |cut -f 1`
typeset -i delta=original-packed
percent=`echo "scale=1;$packed * 100 / $original" |bc`
echo Packed "$original"KB into "$packed"KB\; saved "$delta"KB\; tarball 
is $percent% original size.

echo
echo -n "Do you want to remove the directory? [y/N]: "
read answer
echo $answer |grep -i "^y" > /dev/null
if [ $? -eq 0 ] ; then
        rm -fr "$filename"
fi


Since I can reconstitute the collapsed build directory at any time, I 
can always find out how I built any given installed package.
