[Clfs-support] updating glibc

[mike]

hi all,

i have a good working x86_64 multilib and i try to compile the new blueZ 
package but it fails with an error.

> device.o: In function `disconnect':
> device.c:(.text+0x1847): undefined reference to `g_timeout_add_seconds'
> collect2: ld returned 1 exit status

the blueZ-mailinglist help with the hint to my glibc.
ok, i use /lib[64]/ld-2.5. my question is: can i simply install a new 
glibc beside the version 2.5? and how can i change the linker to use 
then the new library instead the old...?

for understanding:
all installed apps use my ld-2.5 so it must be leave on the hard disk. 
and after installing the new glibc all new apps use this new library, right?
