What problems exactly? Can you give us any error messages? Perhaps there is
an easier workaround.

Meanwhile, my thoughts on your compilation problem:

SunOS 5.8, IMAP 2.2.10, Perl 5.6.1. Similar enough, I think.

Mostly harmless? If you have OpenSSL installed anywhere (your
LD_LIBRARY_PATH seems to indicate that you have) then this is an indication
of problems to come and not harmless at all.

(make runs deleted)

Correct. ld.so.1 is the run time linker. It fails to resolve (find an
implementation of) fdatasync() which is referenced (used) by IMAP.so .

According to man, fdatasync() is an OS function that, roughly speaking,
flushes I/O queues. It is contained in librt. I can verify that in my Cyrus
IMAP build, the fdatasync symbol is provided by /usr/lib/librt.so.1 .

Maybe there is just a "-lrt" missing in your link line. The (link time)
linker would not complain in this case but ld.so would.

Try forcing your linker to include librt:

make LD_OPTIONS=-lrt

This should not hurt anyting and you don't have to explain things to Perl.
Try a "make test".

If the error persists then please send ldd outputs for your IMAP.so:

ldd -s blib/arch/auto/Cyrus/IMAP/IMAP.so

And one without LD_LIBRARY_PATH:

LD_LIBRARY_PATH= ldd -s blib/arch/auto/Cyrus/IMAP/IMAP.so

Perhaps this will give us some pointers. In my experience, LD_LIBRARY_PATH
is evil and should be avoided. But getting rid of the beasty can be a major
PITA.
