If you installed it not in /, maybe it's the link problem again... (ie a // in the links)
does /usr/bin/ipkg-link contains something like:
add () {
echo "*** Adding $PACKAGE"
echo "$files" |
while read line; do
if [ ! -e "/$line" ]; then
# Only if it doesn't already exist.
if [ -d "$PREFIX/$line" ]; then
# It's a directory.
`mkdir "/$line"`
else
# It's a file.
target=`echo ${PREFIX}/${line} | sed -e 's/\/\//\//g'`
`ln -s "$target" "/$line"`
fi
fi
done
}
