Dear sage-developers,
I'm trying to compile sage on Scientific Linux 5.5. The system has gcc
4.6.0 installed, which prompts Sage to install its own spkg of the compiler
because of some bugs. Unfortunately, this doesn't work. From the build log,
I gather that there is a conflict because both a system copy and a sage
copy of the library libgmp are linked (see the snippet below).
Has anyone seen this before? Is there a workaround?
Thanks and best regards,
Timo Kluck
