Upstream has archived old releases of pari-2.5.x and 2.3.x into subfolder. pari-2.x.y (x<7) sources will be found under http://pari.math.u-bordeaux.fr/pub/pari/unix/OLD/2.x/pari-2.x.y.tar.gz rather than http://pari.math.u-bordeaux.fr/pub/pari/unix/pari-2.x.y.tar.gz as is the case for pari-2.7.x.y. So SRC_URI for pari-2.3.5, pari-2.5.0, pari-2.5.1, pari-2.5.2, pari-2.5.3 and pari-2.5.4 ebuilds are wrong.
