[exim] ld.so.1: exim: fatal: libiconv.so.2: open failed: No …

Hi,
I am trying to install version 4.66 on Solaris SPARC machine and when I run "make" it had created a binary. But now having issues with " make install".

Btw when running "make install" getting below error:

make install

Installation directory is /usr/local/exim/bin

ld.so.1: exim: fatal: libiconv.so.2: open failed: No such file or directory

*** Could not run ./exim to find version number ***
*** Exim installation failed ***
make: *** [install] Error 1
pkaturi@gb0882ldaptst01 >sudo make install
mkdir -p /tmp/exim/bin
/tmp/exim/bin created

Please assist.

Thanks,
Prashanth
