Installing libtool 1.5 and 2.2.6a on Linux at the same time

[yersinia]

Hi

A question probably  banal so i apologize in advance but i have not
found any clue.

I'm trying to install on Linux(RHEL5) at the same time, as you can do
with automake and autoconf, libtool 2.2.6a with libtool 1.1.5 on FHS
directories (with --prefix /usr) . But it is not enough use the -
program-suffix=-2.2.6 to  configure: libltdbl for example could
overwrite the library of the e other version. What should I supposed
to do?

Thanks in advance
