[Groff] groff-current fail to compile

[g . esp]

I tried groff upgrade from 1.21 to 1.22.x following LFS instructions:
PAGE=letter ./configure --prefix=/usr && make

With 1.22.1, I encounter 560 warnings while 1.21 only have 15:
Warning: line 28: Unable to locate font 'URWGothicL-Demi!a010015l.pfb' on the 
given path(s)
...
Warning: line 77: Failed to create groff font 'U-AB' by running afmtodit
...
/usr/src/groff-1.22.1/tmac/europs.tmac:5: warning: can't find font `AB'
...
./om.tmac:525: warning: can't find character `A'
...
and so on

As I saw that the issue, source of the numerous warning has been fixed, I tried 
groff-current.
current build fail for me in doc directory with

xpmtoppm ./gnu.xpm | pnmdepth 15 | \                   
          pnmtops -noturn -rle >gnu.eps
