Re: quik question - I apologize for the interruption

First, do not write to me personally. I will not respond to private 
questions like that - if there is an issue that needs explanation, a 
question on a archived  mailing list will benefit all of the community, 
not just you.

As to your question: with any question regarding configure, the 
config.log should be provided. That's the basic rule for any 
configure-based project so you should've been aware of that.

For both make and libtool, configure tries to check their versions by 
invoking them with --version and then trying to match the following regexps:

^GNU Make (3.[89][[:digit:]]|[4-9])
\(GNU libtool.*\) 
(2[[:digit:]]*\.|1\.6[[:digit:]]*\.|1\.5\.[2-9][[:digit:]]+)

So:
- Ensure that the versions of make/libtool you've installed are 
available in the $PATH (and not preceded in $PATH by some outdated 
version, e.g. in your $HOME/bin).
- See what your `make --version` and `libtool --version` print and see 
if it matches the regexps above.

Regards,
Alexey.
