Yeah , true , but
### libncurses.so not found. Please install ncurses development files.
### They usually come in ncurses-devel (RPM) or libncurses-dev (Debian)
packages
###
###
### Readline library detected, but does not seem to work
###
### Building without GNU readline support
Installation prefix ? [/tmp/jason/sage-4.2.1/local]
...for architecture-independent files (share-prefix) ?
this is without the LD_LIBRARY_PATH set , so it's the pari configure script
that needs to be fixed.
