Dear PETSc team, When trying to install PETSc-2.3.3-p11, I get the following output from ./config/configure.py: Traceback (most recent call last): File "./config/configure.py", line 298, in <module> petsc_configure([]) File "./config/configure.py", line 210, in petsc_configure import cPickle ImportError: /usr/lib/python2.5/lib-dynload/cPickle.so: undefined symbol: PyUnicodeUCS4_DecodeRawUnicodeEscape Is there something wrong with my python installation, or what else did I do wrong?
