>How-To-Repeat:
On MacOS X 10.4.5 w/ Xcode Tools 2.2.1 (and probably other revisions),
do:

cd .../pkgsrc/graphics/librsvg2
bmake
>Fix:
There appears to be a bug in the sed command that transforms the
library entry-point names:

sed -e "s,#.*,," -e "s,^[ ]*,," -e "s,^\(..*\),_&," < ./librsvg.def > 
.libs/librsvg-2-symbols.expsym


The expression "s,^[ ]*,," matches and deletes only leading spaces
and not TAB characters.  Each line of "librsvg.def" starts with
a TAB character.

I haven't found where the above sed command is executed.  I've seen
several instances of it in the 'configure' script, and each one has
multiple spaces between the brackets instead of [<space><TAB>]
that would match leading whitespace.

Naive editing has so far not corrected the problem...
