Ok I answer to myself........
The file inet_pton.c seems to be misplaced in the root directory,
instead of being in epan/.
This causes the make to output an error, not finding the inet_pton.c file.
I found a solution to compile correctly on a Japanese website which had
the very same problem in FreeBSD:
http://nhh.mo-blog.jp/ttt/cat1425818/index.html (look for 'inet_pton')
Basically:
in the root directory:
# ./configure [your options]
# *gmake inet_pton.o*
# *gmake inet_pton.lo
**
*# cd epan
# ln -s ../inet_pton.lo
# ln -s ../inet_pton.o
# cd .libs/
# ln -s ../../.libs/inet_pton.o
# make
# make install
I should may be pull up a bug report for this...
