Comment(by vinc17@…):

 I've found the cause: under Mac OS X, emacs needs the eterm-color entry
 from ncurses. However ncursesw only provides Eterm-color (with a capital
 E). With ncursesw 5.6_1, the terminfo data were stored under the pathname
 {{{/opt/local/share/terminfo/e/Eterm-color}}}, but since HFS+ is case-
 insensitive, the file was read and the terminfo data for eterm-color came
 from this file (as a side effect?). Now, with ncursesw 5.7_0, the file is
 stored under the pathname {{{/opt/local/share/terminfo/45/Eterm-color}}},
 i.e. the first letter has been replaced by its ASCII code. And since 'E'
 and 'e' don't have the same ASCII code, ncurses searches for the file
 {{{65/eterm-color}}} and infocmp gives the error:
 {{{
 prunille:~> infocmp eterm-color
 infocmp: couldn't open terminfo file /opt/local/share/terminfo/65/eterm-
 color.
 }}}

 I've tried by adding a file {{{$HOME/.terminfo/65/Eterm-color}}} and this
 workaround solves the problem:
 {{{
 prunille:~> infocmp eterm-color
 #       Reconstructed via infocmp from file: /Users/vinc17/.terminfo/65
 /eterm-color
 Eterm|Eterm-color|Eterm with xterm-style color support (X Window System),
 [...]
 }}}

 Note: there's no such problem under Debian though it has a case-sensitive
 file system, because it solves the problem in another way: emacs defines a
 $TERMCAP environment variable containing the eterm-color definition.
