System: NetBSD 1.4.2 NetBSD 1.4.2 (KIELDRECHT) #15: Wed Jul 11 18:02:11 CEST 2001 i386

	When building package www/gtkgtml there is a script created
	with the name "test":
	When running gmake in that ebrowser directory, at one point 
	the command /bin/sh ../../libtool --mode=link cc  ... is called.
	This apparently uses the test script. The start of the test script
	looks like:

# test - temporary wrapper script for .libs/test
# Generated by - GNU libtool 1.4a (1.641.2.179 2001/02/15 21:55:40)

	and further contains calls of test (where it meant /bin/test),
	some of which are:

if test "${CDPATH+set}" = set; then CDPATH=:; export CDPATH; fi
if test "$libtool_install_magic" = "%%%MAGIC variable%%%"; then
  if test "$libtool_execute_magic" != "%%%MAGIC variable%%%"; then
    if test "X$1" = X--no-reexec; then
    elif test "X`($echo '\t') 2>/dev/null`" = 'X\t'; then
  test "x$thisdir" = "x$file" && thisdir=.
  while test -n "$file"; do
      if test "x$destdir" != "x$file"; then
  test -n "$absdir" && thisdir="$absdir"
  if test -f "$progdir/$program"; then
    if test "$libtool_execute_magic" != "%%%MAGIC variable%%%"; then

	The result is a fork bomb if . is listed in $PATH before

	Now that I'm thinking of it, probably ../../libtool did not even
	mean to invoke ./test, but /bin/test itself, so calling ./test
	was probably wrong in the first place.

	cd /usr/src/pkgsrc/www/gtkgtml
	workaround: change PATH before running make to exclude ".".

	workaround when the make is already in progress: hope you have
	another shell handy, hope you did not run the make as root,
	and attempt to remove or rename the test script. Interrupts
	don't seem to help.

	real fix: teach libtool to use proper full pathnames in all
	scripts it uses and/or generates.

	I will also attempt to send this to bug reporting addresses of
	gnome and libtool.
