here, my analysis

perl-gd.mk contains :
    PERL_GD_CONF_OPT = \
    -options=FT,PNG \
    -lib_gd_path=$(STAGING_DIR)/usr \
    -lib_ft_path=$(STAGING_DIR)/usr \
    -lib_png_path=$(STAGING_DIR)/usr \
    -lib_zlib_path=$(STAGING_DIR)/usr \
    -ignore_missing_gd

when all these options are honored, the output of the configure step
looks like :

    Included Features:          FT,PNG
    GD library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr
    FreeType library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr
    PNG library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr
    Zlib library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr

here, we have

    Included Features:          GD_XPM GD_JPEG GD_FONTCONFIG
GD_FREETYPE GD_PNG GD_GIF GD_GIFANIM GD_OPENPOLYGON GD_UNCLOSEDPOLY
GD_ANIMGIF GD_FTCIRCLE VERSION_33
    GD library used from:       /usr
    FreeType library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr
    PNG library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr
    Zlib library used from:
/scratch/peko/host/usr/arm-buildroot-linux-uclibcgnueabi/sysroot/usr

so, at link time, we have problem with native libraries for GD, Gif,
Jpeg and Xpm.
