I followed the solution proposed by Jianxin, and it worked fine!
After that I guessed which was the difference wit the MacbookAir 
installation, where /python27_2.7.18-1 (one) smoothly built on May, 6. 
Here are the outputs for iMac AFTER the symlink and MacbookAir:
iMac:
/Library/Developer/CommandLineTools/SDKs:
total 0
lrwxr-xr-x  1 root  wheel   15 23 Feb 12:55 MacOSX.sdk@ -> MacOSX10.15.sdk
drwxr-xr-x  7 root  wheel  224  5 Jan 15:19 MacOSX.sdk 1/
lrwxr-xr-x  1 root  wheel   10  7 Jun 11:30 MacOSX10.14.sdk@ -> MacOSX.sdk
drwxr-xr-x  7 root  wheel  224 23 Feb 12:57 MacOSX10.14_orig.sdk/
drwxr-xr-x  8 root  wheel  256 23 Feb 12:58 MacOSX10.15.sdk/

MacbookAir:
/Library/Developer/CommandLineTools/SDKs:
total 0
lrwxr-xr-x  1 root  wheel   15 23 Feb 18:44 MacOSX.sdk@ -> MacOSX10.15.sdk
drwxr-xr-x  7 root  wheel  224  9 Dec 14:42 MacOSX.sdk 1/
lrwxr-xr-x  1 root  wheel   10 12 Oct  2019 MacOSX10.14.sdk@ -> MacOSX.sdk
drwxr-xr-x  8 root  wheel  256 23 Feb 18:46 MacOSX10.15.sdk/

For some reason (mysterious for me) the two sdk installations didn't 
proceed along the same path, even if I always tried to keep Fink 
installations to proceed in parallel each other!
Last question: should I keep MacOSX10.14_orig.sdk or remove it?
Thanks so much for Hanspeter and Jianxin help. Cheers,
