That's the date for installation. I was using the courier-imap and switched
to dovecot.
Not changed since then.

Believe me, it doesn't :(

Yes I did compile it by myself using the "configure; make " way, with the
following command:
CPPFLAGS="-I/usr/local/clucene/include -I/usr/local/libtextcat/include
-I/usr/local/openssl-1.0.1e/include" LDFLAGS="-L/usr/local/clucene/lib
-L/usr/local/libtextcat/lib -L/usr/local/openssl-1.0.1e/lib" ./configure
--prefix=/usr/local/dovecot --with-ssl=yes --with-stemmer --with-lucene
--with-zlib

( also tried with --without-shared-libs or without it  )

The problem ( as usual ) arise with the openssl libs that solaris ships, as
they are always missing some parts ( basically for the export laws solaris
adhere :) )
If I compile with the internal (open)ssl libs it won't even finish the
compilation :(

 Being that I'm the only one administering this machine I'm sure it would
not  ;)

2. Do not use LD_LIBRARY_PATH in the run time environment.  Instead use

That's the important point, but please read on.

 That's fine with me, ( and eventually I will try to modify all the
makefiles, but I hoped it would have already been done by configure ( wich
obviously has not :)

I will try too ( but wouldn't be nice if the configure tool would do that
for us ? )

Interesting:
 root at puma dump -Lv dovecot | grep RUN
[10]    RUNPATH
 /usr/local/dovecot/lib/dovecot:/usr/local/lib:/usr/ccs/lib:/lib:/usr/lib:/usr/sfw/lib
so it's obviously missing the openssl libraries

Yes, although not the one I want:
root at puma ldd -r imap-login | egrep "ssl|crypto"
        libssl.so.1.0.0 =>       /usr/lib/libssl.so.1.0.0
        libcrypto.so.1.0.0 =>    /usr/lib/libcrypto.so.1.0.0

At the moment I've applied a workaround by creating a fake script that
change the library path on execution:
=========================================================================
root at puma cat imap-login
#!/bin/sh
LD_LIBRARY_PATH=/usr/local/openssl-1.0.1e/lib:$LD_LIBRARY_PATH

export LD_LIBRARY_PATH
exec /usr/local/dovecot/libexec/dovecot/imap-login.orig
=========================================================================
and it's working but is not something I really like.

Would you ( or could ) show me where to replace -R and -L on Makefile(s) to
fix the runpath trouble ?

I've tried the following:
CPPFLAGS="-I/usr/local/clucene/include -I/usr/local/libtextcat/include
-I/usr/local/openssl-1.0.1e/include" LDFLAGS="-L/usr/local/clucene/lib
-L/usr/local/libtextcat/lib -L/usr/local/openssl-1.0.1e/lib
 -R/usr/local/openssl-1.0.1e/lib " ./configure --prefix=/usr/local/dovecot
--with-ssl=yes --with-stemmer --with-lucene --with-zlib
and it seems to work:

root at puma dump -Lv ./src/imap-login/.libs/imap-login | grep RUN
[14]    RUNPATH
 /usr/local/dovecot/lib/dovecot:/usr/local/lib:/usr/local/openssl-1.0.1e/lib:/usr/ccs/lib:/lib:/usr/lib:/usr/sfw/lib

I will try this weekend to install the new binary and see if it has done
the magic.

BTW, thanks in advance for your time
