I compiled and installed freeradius-1.0.3 on debian sarge. It runs.
But when using rlm_eap_ttls-1.0.3.so I'm having the same problem
described six months ago by Julien (see below).

Then I tried the latest freeradius-snapshot-20050615 but I get errors in
the install phase:

*** Warning: Linking the shared library rlm_eap_peap.la against the
loadable module
*** rlm_eap_tls.so is not portable!

collect2: ld returned 1 exit status
libtool: install: error: relink `rlm_eap_peap.la' with the above command
before installing it

Cna somebody give me any hints how to get out of this problem?

Yes. The libltdl in Debian includes a patch from the CVS version of
libtool, which breaks the linkage used by rlm_eap_ttls and rlm_eap_peap
into rlm_eap_tls. Try 1.1.0, which should work with the libltdl in
Debian/sarge or Debian/sid.
