I have already found that out, the problem is that my.processTransaction()
silently refuses to install.

#!/usr/bin/python

import yum, os, sys

# setup base objects
my = yum.YumBase()

# someplace you can write to as your user
my.conf.basecachedir = '/tmp/whereever'
if not os.path.exists(my.conf.basecachedir):
    os.makedirs(my.conf.basecachedir)
my.conf.cache = 0
my.repos.setCacheDir(my.conf.basecachedir)

class cb(object):

    def event(self, state, *data):
        try:
            print state,yum.callbacks.PT_MESSAGES[state],data
        except:
            print state,data

my.install(name='xpdf')
my.install(name='xwnc')

my.resolveDeps()

for m in my.tsInfo.getMembers():
    print m.name

my.processTransaction(callback=cb())


This is the output when it s run as a user:

xpdf
xwnc
10 Downloading Packages ()
11 11 ([<yum.sqlitesack.YumAvailablePackageSqlite object at 0x956744c>,
<yum.sqlitesack.YumAvailablePackageSqlite object at 0xc525bac>],)
20 Check Package Signatures ()
30 Running Test Transaction ()
Running rpm_check_debug
40 Running Transaction ()

And this is what I get as root:

xpdf
xwnc
10 Downloading Packages ()
11 11 ([<yum.sqlitesack.YumAvailablePackageSqlite object at 0x95e828c>,
<yum.sqlitesack.YumAvailablePackageSqlite object at 0xc52632c>],)
