[gentoo-user] problems with csound ebuild

hello list,

i need some help to come up with an ebuild for csound (a language for
sound synthesis). 

csound uses scons and then installs files using a script called
install.py. compilation goes fine. 

executables, libraries, plugins and header files are correctly
installed (under /usr/bin, /usr/lib, /usr/lib/csound/plugins/
and /usr/include/csound/ respectively)

but i'm having a bunch of messages like this when it comes to installing
localization files:

 === Installing Localisation files ===
ACCESS DENIED  unlink:    /usr/share/locale/de/LC_MESSAGES/csound5.mo
install: cannot remove `/usr/share/locale/de/LC_MESSAGES/csound5.mo':
Permission denied
 *** error copying /usr/share/locale/de/LC_MESSAGES/csound5.mo

this is the summary:

------------------ ACCESS VIOLATION SUMMARY --------------------------- 
LOG FILE = "/var/log/sandbox/sandbox-15019.log"

unlink:    /usr/share/locale/de/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/en_GB/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/en_US/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/es_CO/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/fr/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/it/LC_MESSAGES/csound5.mo
unlink:    /usr/share/locale/ro/LC_MESSAGES/csound5.mo
------------------------------------------------------------------------

i can circumvent this emerging with FEATURES="-sandbox", but i'd like
to solve this in a cleaner way.


the relevant (i think) part in the script is this:

print ' === Installing Localisation files ==='
xmgList = findFiles('.', '.+\\.xmg')
if xmgList.__len__() > 0:
    err = installFiles(xmgList, xmgDir)
    installErrors = installErrors or err
else:
  xmgList = ['de', 'en_GB','en_US', 'es_CO', 'fr', 'it','ro']
  for i in xmgList:
    makeDir(concatPath([xmgDir, i, 'LC_MESSAGES']))
    src = 'po/' + i + '/LC_MESSAGES/csound5.mo'
    fileName = concatPath([xmgDir, i, 'LC_MESSAGES/csound5.mo'])
    err = runCmd(['install', '-p', '-m', '0644', src, fileName])
    if err == 0:
        addMD5(fileName, fileName)
        print '  %s' % fileName
    else:
        print ' *** error copying %s' % fileName
        installErrors = installErrors or err


the ebuild is attached, any help greatly appreciated.

best,

lj
