Ran sudo ldconfig
In /etc/ld.so.conf.d/libc.conf I already see /usr/local/lib.
Very strange, since install seemed to go through fine.
What does
nm /usr/local/lib/libgretl-1.0.so.16.0.0 | grep libgretl_init
say? You should see something resembling
00000000001479b0 T libgretl_init
Possibly also relevant, what about "cc -v" and "ld -V"?

Does /usr/local/lib/libgretl-1.0.so actually exist, and point to an
valid library file such as libgretl-1.0.so.16.0.0?
If not, the installation was not successful; but if so, you might
need to tell the linker to update its cache:
sudo ldconfig
and/or if /usr/local/lib is not a directory known to the linker you
may have to add an entry for it under /etc/ld.so.conf.d.
