OK. So if 'ht:Pack' is undefined, then either the 'ht' library is not
found, or it somehow has the wrong contents.
$ file <picoLispDir>/lib/ht
say? Is it perhaps incompatible to your 'picolisp' executable (e.g.
remained from some other build)?
/lib/ht: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV),
I builded the 64-bit version again, got a new ht file and 'ht:Pack' is
defined. (The timestamp on the files showed me I builded the 32-bit on
top of the 64-bit)
And now the 32-bit version is showing 'ht:Pack' undefined :)
Better not run them in one installation?
