Sure - LD_LIBRARY_PATH and friends.

Everyone does this all the time. I run glibc 2.1.

Then fix it some more. Find out what else is needed. Smetimes it's not
obvious. You also want to control secondary linkages .. this is not
handled well by LD_LIBRARY_PATH and the solution is usually to run
with ld.so --library-path ... instead.

Keep adding. Locate the crash pint and replace that library.

It matters.

Doesn't matter - you know better than it.
