[GiNaC-list] Installation ginac(1.4) + cln(1.1.13) on powermac

[Hans-Jürgen Greif]

Hi to all,

because octave can't install symbolic package, I have tried to  
install ginac on powermac G4 v. 10.4.10. The ginac configure script  
ends with:

checking for pkg-config... /sw/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for CLN... configure: error: Package requirements (cln >=  
1.1.6) were not met.
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively you may set the CLN_CFLAGS and CLN_LIBS environment  
variables
to avoid the need to call pkg-config.  See the pkg-config man page for
more details.
________________________

I have no experience with pkg-config, so I decided to use  
environments variables
bash shell:

declare -x CLN_CFLAGS="-I/usr/local/include/cln"
declare -x CLN_ LIBS="-L/usr/local/libs/ -lcln"

for installed cln 1.1.13 which is definitely greater (newer)  as 1.1.6.

However, this does not work. Can anyone tell to me, how to set the  
variables above. Or can anyone give a pkg file to handle this problem?

Sincerely,
  Hans-Jürgen  Greif
