Make Failure with tin on sparc Solaris 9

I am trying to compile tin (1.7.5 release 20040615 sparc-sun-solaris2.9) on a 
SPARCstation 20 with Solaris 9.

I am receiving the following error message during make:

ld.so.1: ./makecfg: fatal: libiconv.so.2: open failed: No such file or directory
*** Signal 9
make: Fatal error: Command failed for target `tincfg.h'
Current working directory /home/skidmore/downloads/tin-1.7.5/src
*** Error code 1 (ignored)

libconv.so does in fact exist on my system:

bash-2.05$ locate libiconv.so.2
/usr/local/lib/libiconv.so.2

Also, /usr/local/lib is in my PATH in .bash_profile

bash-2.05$ echo $PATH
/usr/bin:/usr/sbin:/usr/sbin:/usr/dt/bin:/usr/openwin/bin:/bin:/usr/ucb:/usr/loc
al/bin:/opt/sfw/bin:/usr/ccs/bin:/home/skidmore/opera/bin:/usr/local/lib

Do I need to add the path to libiconv.so.2 somewhere else in order to do a 
successful make?

Thanks,
Barry
