On a machine running Debian testing, I have been able to upgrade my sage
installation from 6.9beta1 to 6.9beta3 then to 6.9rc3, but I have a
(probably small) problem with sage-specific version of ncurses which break
the testing suite.
Launching "make ptestlong gives me the following :

Thinking that this was possibly a problem with my library system, I filed
the #799910 bug report to Debian, which got me an answer :

Possibly LD_LIBRARY_PATH is set in user's environment, causing bash
to become confused about which library to use. I seem to recall that
a Debian guideline for packaging says to not use the rpath feature
(which would prevent this problem). It is not a bug in ncurses, but
a problem with the user's environment or custom configuration.
As it is, there are a few possible solutions (by the user):
+ repair the environment (i.e., dropping
/usr/local/sage/local/lib from LD_LIBRARY_PATH)
+ remove the conflicting library from /usr/local/sage/local/lib
Then a second :
[ ... Snipping the previous messages ]
This is a local version of libtinfo.so.5, the one shipped in the
libtinfo5 package does have this version information. Move your locally
installed ncurses libraries out of the way, or rebuild them passing
"--with-versioned-syms" to the configure script.
I checked that this happens also when I force installing Sage's GCC (
SAGE_INSTALL_GCC=YES) in a scratch installation (i. e. after make distclean).
I also checked that this happens on another Debian installation (somewhat
different).
So a couple of questions :
1. Is this specific to my installation(s) ?
2. Whar should I do ?
3. Should I file a Trac ticket ?
Sincerely yours,
