[HarfBuzz] How to uninstall harfbuzz?

[Kelvin Ma]

Because it doesn't work? Here I tested with the simplest possible program,
from sample.py

#!/usr/bin/python3.5
# -*- coding: utf-8 -*-

import sys
import array

from os import environ
environ['LD_LIBRARY_PATH'] = '/usr/local/lib/girepository-1.0'
environ['GI_TYPELIB_PATH'] = '/usr/local/lib/girepository-1.0'

from gi.repository import HarfBuzz as hb
from gi.repository import GLib

fontdata = open(sys.argv[1], 'rb').read ()
text = sys.argv[2]
# Need to create GLib.Bytes explicitly until this bug is fixed:
# https://bugzilla.gnome.org/show_bug.cgi?id=729541
blob = hb.glib_blob_create (GLib.Bytes.new (fontdata))
face = hb.face_create (blob, 0)
del blob
font = hb.font_create (face)
upem = hb.face_get_upem (face)
del face
hb.font_set_scale (font, upem, upem)
hb.ot_font_set_funcs (font)

buf = hb.buffer_create ()
class Debugger(object):
    def message (self, buf, font, msg, data, _x_what_is_this):
        print(msg)
        return True
debugger = Debugger()
hb.buffer_set_message_func (buf, debugger.message, 1, 0)

hb.buffer_add_utf32 (buf, array.array('I', text.encode('utf-32')), 0, -1)

hb.buffer_guess_segment_properties (buf)

hb.shape (font, buf, [])
del font

infos = hb.buffer_get_glyph_infos (buf)
positions = hb.buffer_get_glyph_positions (buf)

for info,pos in zip(infos, positions):
    gid = info.codepoint
    cluster = info.cluster
    x_advance = pos.x_advance
    x_offset = pos.x_offset
    y_offset = pos.y_offset

    print("gid%d=%d@%d,%d+%d" % (gid, cluster, x_advance, x_offset,
y_offset))

This works correctly when Harfbuzz is installed in usr/local/.

However, if I sudo make uninstall, run ./configure --with-gobject
--enable-introspection --prefix=/home/kelvin/HB, and make install, and
change the environment variables to

environ['LD_LIBRARY_PATH'] = '/home/kelvin/HB/lib/girepository-1.0'
environ['GI_TYPELIB_PATH'] = '/home/kelvin/HB/lib/girepository-1.0'

The script crashes like this:

~$ ./hbt.py NocturnoDisplay-Bk.otf effectiveness
./hbt.py:11: PyGIWarning: HarfBuzz was imported without specifying a
version first. Use gi.require_version('HarfBuzz', '0.0') before import to
ensure that the right version gets loaded.
  from gi.repository import HarfBuzz as hb

And yes, libharfbuzz-gobject.so.o is in the folder:

~/HB/lib$ ls
girepository-1.0                  libharfbuzz.la
libharfbuzz-gobject.la            libharfbuzz.so

libharfbuzz-gobject.so.0.10200.7  pkgconfig
