-lcln is missing from your link command because your pkg-config doesn't 
In your config.log the command for pkg-config is set to /bin/true ! Not 

To find the reason you can try the following things:

Issue the command

pkg-config cln --libs

and see what happens. It should give -lcln as an answer.

If the command is not found -> repair your pkg-config installation.
If the command says it doesn't know about cln -> check your 
PKG_CONFIG_PATH variable and where cln.m4 is installed. BTW, did you 
compile cln yourself or is it a binary package from your distribution?

In any case, after a new configuration of GiNaC look in config.log for 
the line PKG_CONFIG='... and if you find a path to pkg-config there, 
then everything should be fine. Otherwise, please complain again!
