CTAN's `tex-gyre' package does not contains fontconfig conf file for TeX
Gyre files.
Ubuntu's `fonts-texgyre' package contains it.
(Both packages also contain TeX Gyre OTF files.)

Only the installation of CTAN package `tex-gyre' is not enough.
configure script searches TeX Gyre OTF files (texgyreschola-regular.otf
etc.) by fontconfig fc-list utility.
If the fontconfig conf file does not exist, fc-list can not find them,
even if they exist.

If configure option `--with-texgyre-dir' is used, configure script does
not use fc-list.
In that case, configure script uses the option specified directory to
find TeX Gyre OTF files.

In other words, either of the following is required:

 - TeX Gyre OTF files and fontconfig conf file for them (same as
Ubuntu's `fonts-texgyre')
 - TeX Gyre OTF files and configure option `--with-texgyre-dir' to
specify them
