------------------------


On Ubuntu 10.04 LTS libc version detection fails in util/arch. The reason is that now (around line 244) strings libc.so.6 returns

GNU C Library (Ubuntu EGLIBC 2.11.1-0ubuntu7) stable release version 2.11.1, by Roland McGrath et al.

where the version number appears twice. The subsequent tests get a string like "11\n11" instead of just "11" and the shell complains that
the syntax of the if conditions is wrong.

I fixed it by adding uniq to this line

libc_version=`echo $libc_string | tr ' ,' '\n' | grep "2\." | cut -f 2 -d "." | uniq`

   ------- Additional comments from olesen Tue May 18 02:09:36 -0700 2010 -------
These problems with parsing the libc output recur with some frequency.
If the Solaris sed can handle the following type of expression, I think we should use it.
It saves a number problems and several process forks:

/lib/libc.so.6 | sed -ne '1s/^GNU C Library.*version *2\.\([0-9][0-9]*\).*$/\1/p'
