[BRLTTY] Tcl error?

[Raoul MEGELAS]

Hello Dave,
Compiling brltty with the last change gives  the following error 
On ./autogen:
error reading "file5": invalid or incomplete multibyte or wide character
    while executing
"gets $stream line"
    (procedure "getDependencies" line 13)
    invoked from within
"getDependencies $sourceFile"
    ("foreach" body line 5)
    invoked from within
"foreach sourceFile [glob -nocomplain [file join $buildDirectory "*.$sourceExtensionsGlob"]] {
      regsub {^(\./)+} $sourceFile {} sourceFile
      i..."
    ("foreach" body line 2)
    invoked from within
"foreach buildDirectory [set buildDirectories [getBuildDirectories]] {
   foreach sourceFile [glob -nocomplain [file join $buildDirectory "*.$sourceExt..."
    (file "Tools/gendeps" line 158)

Note:  OS Darwin 14  with brew .
Is this related to the last tcl change?
