configure and libjpeg version on openSUSE 10.2

[Reiner Steib]

Hi,

on openSUSE 10.2, configure (updated from CVS today) complains about
libjpeg being too old: "not version 6b or later".

So configure decided not to use my libjpeg.

According to the time stamps, it used the expected header file and
library:

| $ ls -lu `locate jerror.h`; ls -lu `locate libjpeg.so`
| -rw-r--r-- 1 root root 13989 2007-03-24 14:53 /usr/include/jerror.h
| [...]
| [...]     17 2007-03-24 14:53 /usr/lib/libjpeg.so -> libjpeg.so.62.0.0
| [...]     16 2007-03-24 14:50 /usr/lib/libjpeg.so.6 -> libjpeg.so.6.0.1
| [...] 155043 2007-02-18 17:13 /usr/lib/libjpeg.so.6.0.1
| [...]     17 2007-03-24 14:53 /usr/lib/libjpeg.so.62 -> libjpeg.so.62.0.0
| [...] 127160 2007-03-24 14:53 /usr/lib/libjpeg.so.62.0.0

The RPM information from SUSE claim that it *is* "version 6b", see the
lines "Source RPM".  Is the configure test[1] broken or is SUSE's
information wrong?  How can I find out?
