[Ecls-list] Can't compile the cvs srcs

[IOL1]

I'm pretty sure this is my fault, but the compilation on my Debian 
testing (Sidux) goes on till I invariably get:

<snip>
;;; Copying ext:encodings;tools.lisp to build:encodings;tools.lisp
;;; Copying ext:encodings;ISO-2022-JP to build:encodings;ISO-2022-JP


Debugger called in: #<process SI:TOP-LEVEL 091c8fc0>.

;;; Copying ext:encodings;ISO-2022-JP-1 to build:encodings;ISO-2022-JP-1
Cannot find the external symbol CURRENT-PROCESS in #<"MP" package>.

Available restarts:

1. (SUSPEND-DEBUG) Put this process back on debugger's waiting list.
2. (QUIT-DEBUGGER) Quit debugger level 1.

Broken at SI::TPL. In: #<process SI:TOP-LEVEL 091c8fc0>.

Am I missing some library, or what?

Any suggestion is greatly appreciated, I'd really like to try this release.

Thanks so much.

P.S.: my ./configure cheatcodes from older releases compilations:

./configure --prefix=$HOME/Lisp/ECL --exec-prefix=$HOME/Lisp/ECL/execs 
--enable-threads=yes --enable-boehm=auto --enable-unicode=yes 
--enable-longdouble=yes --enable-c99complex=yes --enable-asmapply=yes
